Previously, if a hidden, aria-owned subtree was shown and aria-activedescendant was simultaneously targeted inside it, aria-activedescendant would fail.
This occurred because when we processed insertions, the presence of aria-owns meant we didn't create the subtree.
This meant that when we processed aria-activedescendant (which occurred before relocations), the active descendant didn't exist yet.
To fix this, we now process generic notifications (including aria-activedescendant) *after* relocations.

This patch also incidentally fixes a bug where getContentWindowOrOpenURI
returned the top-level browser window rather than the new content window when
passed OPEN_NEWWINDOW for the `aWhere` parameter. This was not the expected
behavior, and was a potentially major footgun for any new users who expected
to always get the content window for the URL they were loading, rather than
sometimes getting a chrome browser window instead.

Editor creates a `<br>` element when it's root element is empty.
Then, it's stored by `TextEditRules::mBogusNode` and used for checking
whether the editor is empty quickly. However, this `<br>` element has
`mozeditorbogusnode` attribute whose value is `true`. However, adding or
removing the attribute is not cheap and web apps can refer such illegal
attribute.
Therefore, this patch makes `HTMLBRElement` take a specific flag whether
it's a bogus node or not. However, this means that this hacky thing will be
exposed outside editor module. For making what is the bogus node clearer,
this patch calls the such `<br>` elements as "padding `<br>` element for
empty editor". So, this patch also includes a lot of renaming methods and
variables, and modifying related comments.

Normally, the OuterDocAccessible is created first and the DocAccessibleParent for a remote document is created after that.
So, we get the OuterDocAccessible and call DocAccessibleParent::SendParentCOMProxy when the DocAccessibleParent is constructed (BrowserParent::RecvPDocAccessibleConstructor).
However, sometimes, the OuterDocAccessible is created *after* the DocAccessibleParent.
This sometimes happens for extension popups, for example.
In that case, we previously never sent the parent COM proxy.
Aside from leaving the remote document with a null parent, this also meant we never sent any events for the document, since events are buffered for remote documents until the parent COM proxy is received.
This effectively left the remote document (e.g. extension popup) inaccessible.
Now, we also call SendParentCOMProxy in the OuterDocAccessible constructor.
Note that this doesn't result in duplicates because if the OuterDocAccessible was created first, there won't be a DocAccessibleParent for the remote document yet, so this code won't run.
That said, if the OuterDocAccessible is recreated (e.g. due to frame reconstruction), we may call SendParentCOMProxy again.
This should be okay, but it required an assertion in DocAccessibleChild::RecvParentCOMProxy to be tweaked.

Previously, DocAccessibleParent::AddChildDoc used the presence of a BrowserBridgeParent to determine whether the child document was in a different process to the parent document.
While this is normally the case, there can be a point while the embedded document is loading where there is a temporary document in the same (embedder) process.
In this case, we tried to get the COM proxy for the child document.
For a child document in the same process, this isn't available yet, so this caused infinite recursion (stack overflow) in ProxyAccessible::GetCOMInterface.
Instead of using the presence of BrowserBridgeParent, first check whether the child document is at the top level of its content process.
If it isn't, the document is in the same process as its parent.
Also, add a DIAGNOSTIC_ASSERT to ProxyAccessible::GetCOMInterface which will fire if no COM proxy or MSAA child id has been set.

`NS_FRAME_IS_DIRTY` being set on a frame has always meant that that
frame and all of its descendants need to be reflowed. What the main
patch on this bug is changing is when it gets propagated to descendants;
prior to that patch it gets propagated during reflow, whereas after the
patch it gets propagated when the bit is set. This means that
`NS_FRAME_IS_DIRTY` is now (after the patch) a somewhat more reliable
indicator of whether a frame requires reflow than it was before.
However, this has a strange interaction with the particular sequence of
operations that test_list.html performs. In particular, test_list.html:
(1) makes a style change that requires reflow,
(2) flushes style (but not layout), and
(3) gets the name of an accessible whose layout was dirtied by the style change.
Getting this name ends up here:
```
nsTextFrame::GetRenderedText at layout/generic/nsTextFrame.cpp:9600
nsTextEquivUtils::AppendTextEquivFromTextContent at accessible/base/nsTextEquivUtils.cpp:127
nsTextEquivUtils::AppendFromAccessible at accessible/base/nsTextEquivUtils.cpp:174
nsTextEquivUtils::AppendFromAccessibleChildren at accessible/base/nsTextEquivUtils.cpp:162
nsTextEquivUtils::GetNameFromSubtree at accessible/base/nsTextEquivUtils.cpp:39
mozilla::a11y::Accessible::NativeName at accessible/generic/Accessible.cpp:1991
mozilla::a11y::HyperTextAccessible::NativeName at accessible/generic/HyperTextAccessible.cpp:1760
mozilla::a11y::Accessible::Name at accessible/generic/Accessible.cpp:149
mozilla::a11y::xpcAccessible::GetName at accessible/xpcom/xpcAccessible.cpp:245
NS_InvokeByIndex at xpcom/reflect/xptcall/md/unix/xptcinvoke_asm_x86_64_unix.S:106
```
What the main patch in the bug has changed is whether this `nsTextFrame`
has the `NS_FRAME_IS_DIRTY` bit set at this point. This means that
`GetRenderedText` will bail out without reporting the text, because the
frame is marked dirty.
On the assumption that this action -- getting accessible names while
frames are dirty -- is an artificial situation set up in the test and
not a real-world situation that we need to care about, I'm proposing
that we make the straightforward adjustment to the test: flush layout
in addition to flushing style at step (2) above, so that the test works
again. As long as that assumption is correct, I think this should be
fine. (I'd note that this is the *only* test that breaks as a result of
the patch.)
If, on the other hand, we actually do care about what accessible names
return while layout state is dirty and reflow is needed, we should
probably improve `nsTextFrame::GetRenderedText` so that it can somehow
report useful state even when `NS_FRAME_IS_DIRTY` is set, or something
else more complicated.

When a client wants to fetch all accessible children, the COM handler uses handlerProvider::get_AllChildren in the content process to optimize cross-process retrieval of all children.
This works fine for iframes rendered in the same content process, just as it does for other accessibles.
However, for out-of-process iframes, HandlerProvider::get_AllChildren will fail.
This is because we only send down an IDispatch COM proxy for the embedded document, but get_AllChildren will try to QueryInterface this to IAccessible2 to reduce QI calls from the parent process.
Because the content process is sandboxed, it can't make the outgoing COM call to QI the proxy from IDispatch to IAccessible2 and so it fails.
Since an iframe only has one child anyway, we don't need the bulk fetch optimization offered by HandlerChildEnumerator or even IEnumVARIANT.
Therefore, we explicitly tell the client this interface is not supported, which will cause the oleacc AccessibleChildren function to fall back to accChild.

They should be CamelCase, and that's what most of them already do. This converts

For the ones that already used `e` or `k` prefixes, I've mostly done:
for file in $(rg Type::e layout | cut -d : -f 1 | sort | uniq); do sed -i 's#Type::e#Type::#g' $file; done
For the ones that used uppercase, I've removed the prefix if it was already in

nsITabParent is exposed to frontend code and is generally used as a representation of a remote tab. We could just rename the interface to nsIBrowserParent and worry about it later, but I think it's better to rename the interface to nsIRemoteTab so that we can later work on splitting the interface away from the PBrowser protocol.

This patch marks `ScrollContentIntoView()` as `MOZ_CAN_RUN_SCRIPT` and changing
some callers of them to guarantee thar their parent callers are also safe.
Additionally, this patch moves it from `nsIPresShell` to `PresShell` because
all callers can refer `PresShell` directly.
Unfortunately, this patch changes a lot of methods in autocomplete and satchel
since this patch needs to mark some interface methods as `can_run_script` and
they are called each other. This means that autocomplete module is really
sensitive like editor module. Perhaps, autocomplete and satchel should do
scroll asynchronously and unmark some of them as `MOZ_CAN_RUN_SCRIPT` again.

Sometimes, we use aria-activedescendant targeting something which isn't actually a descendant.
This is technically a spec violation, but it's a useful hack which makes certain things much easier.
For example, we use this for "fake focus" for multi select browser tabs and Quantumbar autocomplete suggestions.
This already worked previously; the accessible received a focus event and the focused state.
However, it did *not* receive the focusable state.
This is because the code which applies the focusable state for potential active descendants only works for descendants.
It really doesn't make sense for something to be focused when it isn't focusable.
In fact, this is an a11y test failure when it occurs.
So, if the active item has the focused state, ensure we expose the focusable state too.
