The crash occurs when dispatching a user input event which is a default action
of a raw user input event like `click` event caused by `mouseup` event if
the raw event's `isTrusted` is set to `false` accidentally during dispatch.
User input events are fired in the main process first. Then,
`EventStateManager` sends it to remote process from `PostHandleEvent()` if
necessary. However, at this time, `WidgetEvent::mFlags::mDispatchedAtLeastOnce`
is never rest, but its only referrer, `EventDispatcher::DispatchDOMEvent()`
assumes that when it's `true`, `WidgetEvent::mFlags:mIsBeingDispatched` is
`false`. Therefore, only in content process, `mouseup` event's `isTrusted` is
set to `false` by `EventTarget.dispatchEvent()` even while it's being dispatch.
And also the trusted state will be used for creating next event which is part
of the default action.
https://searchfox.org/mozilla-central/rev/6566d92dd46417a2f57e75c515135ebe84c9cef5/dom/events/EventDispatcher.cpp#1121,1126,1130-1131,1135,1138,1143
Therefore, this patch makes `WidgetEvent::mFlags` reset `mDispatchedAtLeastOnce`
when it's copied across process boundary and make
`EventDispatcher::DispatchDOMEvent()` won't modify being dispatched events for
avoiding any odd issues.
Unfortunately, this patch adds "expected: FAIL" to the new WPT test only on
Windows. The failure reason is still unclear. I cannot reproduce the failure
on my Windows environment, but on Try Server, it fails permanently since
the driver succeeds to send the mouse click, but the button never receives
`mouseup` nor `click` event.

Even though context menu key events are caused by a key press, they get handled as mouse events.
Because the parent process FocusManager only knows about top level remote browsers, the event can only be targeted to a top level remote browser, even if the focus is actually in an OOP iframe.
To fix this, when dispatching cross-process events, handle context menu key events the same way we handle normal keyboard events; i.e. use the focused remote browser.

We were keeping nsDocShell::mHistoryId and nsDocShell::mOSHE as keys. They
weren't quite good because:
1. While loading an iframe, they were being registered twice with the same
ids(for about:blank and the real URL) sometimes.
2. It wasn't possible to access to the parent mHistoryId and mOSHE from a child
processes if the parent is in a different process. That may not be the case for
now, but it will be after fission.
So we had to find other IDs to:
1. Determine the Tab of the frames.
2. Determine the URLs of the frames.
For the first use case, we were using nsDocShell::mHistoryId for that purpose
but that was wrong. The closest thing that we can get to a tab ID is
BrowsingContext ID because they don't change after a navigation. But iframes
have different BrowsingContext's, so we still need to create a tree to
construct a tab content. That can be either in the front-end or capture time.
For the second use case, we were using a key pair of mHistoryId and mOSHE. We
now chose to keep inner window IDs for that purpose. Inner window IDs are
unique for each navigation loads because inner window correspond to each JS
window global objects. That's why we can use that without any problem. But one
problem is that we cannot handle `history.pushState` and `history.replaceState`
changes with that change since window global objects won't change during those.
But that was the best thing we can do after fission. So this will be a small
sacrifice for us to keep that functionality working after fission.
In that patch we also remove the registration/unregistration calls. We are
going to add those calls in the next patch.

The previous change is wrong because the sender shouldn't send selection change

nor selection change notifications.
This patch reverts the change in the if block of previous change and instead
sets `IMEContentObserver::mNeedsToNotifyIMEOfSelectionChange` to `true` if
the sender sends a text change notification. (Note that even if there is

`IMEContentObserver` sends selection change notification only when it receives
a DOM `Selection` change notification received. However, selection range in
plaintext offset may be changed when changing previous content of caret is
changed. In this case, currently we notify IME of only text change and
that causes IME keep caching selection offsets in previous content. This
causes IME queries character rect out of bounds. Therefore, even if
`IMEContentObserver` hasn't received DOM `Selection` change notification,
it should recompute selection range and if it's changed, it should notify
IME of selection change too.

There are a few other functions that check the result of
GetPerceivedScrollingDirections(), but I think if we change this we should
change this consistently.
I also think that if we do this we should rename the method to something like
GetAvailableScrollingDirections() or such.
Anyhow, wdyt? I should also add a test for this if we go with this.

This is what other browsers do, and it does make sense to me, it's useless to
try to scroll a frame with no scroll range in a given direction.
I think all callers of this function should be treated like this, so this is
more like a RFC / feedback request than a patch per se.

Unmasking is an optional style of showing password. Therefore, if callers of
`nsIEditor::Unmask()` specify middle of surrogate pair(s), it may mean that
they want to expand the unmask range from shorter range which does not include
the high and/or low surrogate. Therefore, one of the surrogates is in unmasked
range, we unmask the surrogate pair. However, we handle this in a lot of
places, i..e., we have duplicated code. This can get rid of these duplicates
with making `nsIEditor::Unmask()` expand the range automatically.

In some cases, other tools may show selected content in their UI. E.g.,

masked password.

Now, the anonymous text node has raw value of password so that we shouldn't
allow users to drag the text since another user may have typed the password
and left from the device.
Note that we've supported the operation, however, it does not make sense
since the dragging data is masked text.
Additionally, Chrome also doesn't support dragging text in password fields.
So, we have no reason to support dragging raw value from password fields.

My preference was to annotate most of the failing tests with `fail-if` so that
if they start passing, the `fail-if` needs to be removed and they need to keep
passing. That doesn't work for tests that timeout, or which trigger failures
from their cleanup functions, however, so those tests need skip-if. And tests
with fail in their cleanup functions likely leave the browser in an
inconsistent state for subsequent tests, anyway, so really should be skipped
regardless.
There are some remaining tests which still fail because of crashes. I chose
not to skip them here, but to fix the crashes in separate bugs instead.

Actually, long tap can set focus. But since it uses `nsIFocusManager::FLAG_BYMOUSE` flag, we cannot recognize whether setting focus is by long tap or not.
So I would like to add new flag `FLAG_BYLONGPRESS` and `CAUSE_LONGPRESS` that are by long tap.

The SpecialPowers set*Pref/get*Pref APIs currently use synchronous messaging
to set and get preference values from the parent process. Aside from directly
affecting callers of those APIs, it also affects callers of `pushPrefEnv`,
which is meant to be asynchronous, but is in practice usually synchronous due
to the synchronous messaging it uses.
This patch updates the getPref APIs to use the in-process preference service
(which most callers are expecting anyway), and also updates the callers of
the setPref and pushPrefEnv APIs to await the result if they're relying on it
taking effect immediately.
Unfortunately, there are some corner cases in tests that appear to only work
because of the quirks of the current sync messaging approach. The synchronous
setPref APIs, for instance, trigger preference changes in the parent
instantly, but don't update the values in the child until we've returned to
the event loop and had a chance to process the notifications from the parent.
The differnce in timing leads some tests to fail in strange ways, which this
patch works around by just adding timeouts.
There should be follow-ups for test owners to fix the flakiness.

Some `nsRange` static methods are useful in `StaticRange` and some of them
are used in a lot of places but not related to `nsRange` directly. This
patch moves them into new static method only class, `mozilla::RangeUtils`.

For avoiding confusion between API of `nsRange` and `StaticRange`, I'd like to
rename `nsRange::CreateRange()` to `nsRange::Create()` because
`StaticRange::CreateStaticRange()` is too long name and
`StaticRange::CreateRange()` sounds odd. This patch renames it and changes
related methods to template methods to avoid runtime cost of temporary
`RawRangeBoundary` instance creation.

In general case, we set `IsHandlingUserInput` flag in `PresShell::EventHandler::HandleEventWithCurrentEventInfo()` for user interaction event.
However the interaction could happen on parent process, like e10s select and input date etc., whose dropdown/popup menu is implemented on parent process and it sends the interaction result to content process, then generates/dispatches corresponding event on content process directly. For such case, we need an addition hook before calling the event listener, just like what we do for popup blocker. It also makes more sense that we handle `popup blocker state` and `IsHandlingUserInput` flag at a consistent time.

Before this change, only elements inside the shadow root tree were scanned for the
draggable=true attribute. We now check the flattened tree instead so an element
inside a shadow root can start a drag for an element containing the shadow root.

Unfortunately, `EventChainVisitor` does not grab the `nsPresContext` with
`RefPtr` by itself. Therefore, there is no guarantee of the lifetime without
checking the origin when its subclasses are instantiated. This patch changes
it and subclasses to `MOZ_STACK_CLASS` since only `EventDispatcher::Dispatch()`
creates them in the stack with given `nsPresContext`. Additionally, it's
already been marked as MOZ_CAN_RUN_SCRIPT_BOUNDARY`. Therefore, the
`nsPresContext` instance has already been guaranteed its lifetime by the
caller. For making this fact stronger, this patch marks their constructors
as `MOZ_CAN_RUN_SCRIPT`. Therefore, nobody can create those instances without
guaranteeing the lifetime of `nsPresContext` and `dom::Event`. Note that
it may look like that `mPresContext` of `EventChainPostVisitor` is not
guaranteed. However, `EventChainPreVisitor` which gives `nsPresContext` to it
is also a stack only class. So, it won't be deleted before
`EventChainPostVisitor` instance.
