We have an optimization to avoid an expensive reflow from SetFullZoom, see
mSuppressResizeReflow[1].
That was done because we used to do a full synchronous reflow right after. We no
longer do that, but due to that member we also don't invalidate!
My second patch in this bug changes the behavior of that flag so that we don't
synchronously reflow, but we do invalidate. So in turn this test before the
change wasn't really testing the zoomed code-path since it was using the clean
layout from before the zoom operation.
a11y getBounds and co. don't flush layout (they probably should), but since with
my patch we dirty the frame tree, and dirty frames return bogus offsets, the
test starts failing.
Flush layout explicitly to ensure we're testing the zoomed code path.

This change will bring us on par with what Chrome does. However, if the author makes an error in applying a landmark role to an interactive element, or other element where the landmark role is illegal, as defined in the [WAI-ARIA in HTML specification section 2](https://www.w3.org/TR/html-aria/#document-conformance-requirements-for-use-of-aria-attributes-in-html), the accessible properties will now be that of the landmark role, no longer that of the native host language element. This might make some elements less accessible due to author error than before, but we currently do not know of examples in the wild that actually expose this problem. This could only be solved by applying the rules from said table also in the user agents, but that is not specified anywhere.

Previously, if a hidden, aria-owned subtree was shown and aria-activedescendant was simultaneously targeted inside it, aria-activedescendant would fail.

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

to always get the content window for the URL they were loading, rather than
sometimes getting a chrome browser window instead.
For now, that case just returns null, which is only a minor footgun, rather

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.
