BrowsingContext::ShouldAddEntryForRefresh expects to be passed the current URI,
to determine if it's the same as the URI for the new load (we shouldn't add a
new entry if they are the same). Before this patch, in the child process we call
BrowsingContext::ShouldAddEntryForRefresh from nsDocShell::MoveLoadingToActiveEntry
(nsDocShell::CreateContentViewer -> Embed -> MoveLoadingToActiveEntry), passing
nsDocShell's mCurrentURI. However, by that point nsDocShell::CreateContentViewer
has already set the mCurrentURI to the newly loading URI (through
nsDocShell::OnNewURI). In the parent process we do pass the correct URI to
BrowsingContext::ShouldAddEntryForRefresh, so the session history ends up being
correct, but depending on timing of the IPC messages there's a brief moment where
index and length are incorrect in the child process (child process and parent
process get a different answer from BrowsingContext::ShouldAddEntryForRefresh).
This causes intermittent failures in the test at
docshell/test/mochitest/test_bug1742865.html.

I can see that after navigation, allowJavascript is correctly set for the browsing context, but it seems we need to call
RecomputeCanExecuteScripts() to force it to be applied to the new page. Not sure if doing this here makes sense or if it should be done earlier.
Also there are still other issues with this feature:
- closing the toolbox does not reload the page: meaning JavaScript remains disabled on the page
- similarly all pages which have been put in bfcache will retain the javascript disabled/enabled setting
For the first issue, I wonder if we should force a reload when closing the toolbox (iff javascript disabled was toggled).
And for the second issue, could we invalidate contexts put in bfcache for a given browsing context when we toggle allowJavaScript?
Olli: Does this change make sense at least to fix the basic issue?

Mostly changing XUL attributes to CSS properties, though there are a few
tricky ones:
* test_offsets.xhtml expects the scroller to be full-width, while
modern flexbox would honor width: 200px (so just remove it).
* window_intrinsic_size.xhtml was relying on the div imposing a XUL
min-size (the test is for SetSizeConstraints, bug 1447056). Use
min-height instead as that's what modern flexbox reads. Confirmed
that bug doesn't regress in any case.
* object-fit-contain-png-001.xhtml has a float: left which had no
effect on -moz-box, but which assert with modern layout[1]. In the
future I think we could remove that assert but anyways, for now just
keeping behavior.
* image-size.xhtml has a couple uninvestigated sizing differences. They
didn't seem problematic.
* 579323-1-ref.html changes because the other file has a canvas with
width=100 height=100 which imposes an aspect ratio (which XUL never
honored).
* window_largemenu.xhtml shows a regression, but this never worked on
some platforms (at least Linux+Wayland) and nobody has noticed it in
the browser area, so I suspect we're fine.

Because the parent process lacks information about the current shell
size, the child has to send both the current and the new shell size to
the parent. The parent then applies the delta to the window size. This
can produce different results for calls with the same arguments,

with its new size.
The implementation is replaced by applying the delta in the child.

Implementations of nsIEmbeddingSiteWindow and nsIBaseWindow largely
overlap, and where they don't, the nsIEmbeddingSiteWindow implementation
of the otherwise shared interface is primarily stubbed out with the
exception of Get/SetDimensions().
This patch moves a reimplementation of Get/SetDimensions() from
nsIEmbeddingSiteWindow to nsIBaseWindow. The other methods of
nsIEmbeddingSiteWindow remain covered by nsIBaseWindow.
Get/SetDimensions() can be implemented as part of nsIWebBrowserChrome
where nsIBaseWindow is not necessary. This removes the need for
nsIEmbeddingSiteWindow.
Blur() has also been moved to nsIWebBrowserChrome, as only
nsContentTreeOwner has an actual implementation which we in theory also
want to call from BrowserChild/Parent, but the spec suggests to
"selectively or uniformly ignore calls".
GetVisibility() had an implementation in BrowserChild that pretended to
always be visible. Instead of providing an interface for that,
nsDocShell now handles the not implemented case for tree owners.
nsIEmbeddingSiteWindow::GetSiteWindow() used to call through to
nsIBaseWindow::GetParentNativeWindow().
The Get/SetDimensions() implementation has been replaced with a strongly
typed setter, which is now also used directly from nsGlobalWindowOuter
to avoid problems that come with autodetecting unchanged dimensions,
when the current dimensions are outdated (e.g. immediately reverting a
change can be ignored).

Bug 1805414 will move menu event handling to the DOM.

getting called at all for synthetic clicks, and instead we just fire a
command event synchronously here:

After my patch the command event is fired properly (potentially
asynchronously too) by the regular menu activation machinery, which is
preferable.
* They fire a command event synchronously (even though on some
platforms like macOS activating a context menu item is async).
* They use a totally different codepath from what a user does.
* They don't deal with native menus, etc.
We have a proper API for this (activateItem) which takes a much more
closer codepath to what users do, requires that the menu is shown, etc.
Use that API instead for testing.
As a benefit, tests now do not need to close the context menu manually
when clicking on a menu item (because we trigger the same code path as
users clicking the menu).

Propagate the ability to pass triggeringRemoteType through the desktop frontend
in various places, such that it is set when using the context menu or content
click handler.
Differential Revision: https://phabricator.services.mozilla.com/D161834
This is done using slightly different mechanisms for each of LoadInfo and
nsDocShellLoadState, and will be used in the next part to validate document
loads based on the RemoteType responsible for the load.
For subresource loads, the TriggeringRemoteType is fairly straightforward - it
is the process which created the channel. We can handle this by getting the
current remote type when creating the channel, and then using the remote type
of the sending process when receiving the LoadInfo over IPC to either replace
the triggering remote type, or validate it.
For document loads, the situation is a bit more complex, as there are at least
3 (potentially-)different processes responsible for different parts of the
navigation:
1. The "Triggering Process" is the process which provided the URI to load.
This is also the process which provides the Triggering Principal. This is
the process being tracked in this patch.
2. The "Loading Process" is the process which actually creates the channel and
starts the load. This may be the same as the triggering process, or may be
a different process starting the navigation on behalf of the triggering
process. In general this is the process hosting the current docshell,
though it may be the parent process in the case of parent-initiated loads.
3. The "Final Process" is the process which receives the response and renders
the final document. This isn't known at channel creation time, and is
determined by the result principal and process isolation policy.
This change uses a serializer and special field on nsDocShellLoadState to track
the "Triggering Process" for the load, even as the load state is serialized
between processes by tracking which loads were sent into which content
processes, and matching them up when the parent process sees them again. The
information is then copied into the LoadInfo before configuring the real
channel, so it can be used for security checks.
The "Triggering Process" is overridden to be the parent process for history
loads, as history loads are often started in processes which wouldn't normally
be able to navigate to those pages. This is OK thanks to the changes in part 1
which validate history loads against the real session history when SHIP is
enabled.
Differential Revision: https://phabricator.services.mozilla.com/D161198
With SHIP, we have a copy of the actual SessionHistoryEntry which is
responsible for a history load locally within the parent process. Using this,
we can validate any session history loads coming from the content process to
ensure that they correspond to actual outstanding history loads.
We can't do this for non-SHIP loads, as session history exists only within the
content process.
Differential Revision: https://phabricator.services.mozilla.com/D161197
Previously, we tracked UnstrippedURI on the nsDocShellLoadState and LoadInfo,
and manually filled it in to match the previous load when doing a
LOAD_CMD_RELOAD in nsDocShell. It is more consistent with other load types to
instead store the information in the load state, allowing it to be handled
consistently for reloads and other history operations.
Unfortunately, this patch has some extra complexity right now, as it needs to
support both SHIP and non-SHIP session history. This should disappear in the
future when we switch to using exclusively SHIP.
