When an element with overflow:auto becomes scrollable, either by a style change or growing children, it should become focusable and fire a state change. Same in the inverse.

Changes to attributes such as disabled, contenteditable, and tabindex should cause FOCUSABLE
state changes to be fired when indeed the accessible gains or loses focusability.

addA11yLoadEvent gets the contentWindow and wait for the document from that window to fire the load event.
Enabling the DocumentChannel for parent process load (or here in non-e10s mode) we have one extra event loop before the load starts.
So the window passed to addA11yLoadEvent would have been of the about:blank page.
The current code was based on an observable behaviour which was that the load was occuring synchronously.
DocumentChannel broke that assumption.

This code has pretty much always been broken, we've started to flush
more because we fixed a bug that was not looking at XUL trees inside
shadow DOM in bug 1625991.
We cannot flush layout from a11y tree construction.

We need to do this because we can't rely on the main children cache invalidation.
Also, I don't think this really worked before with cell additions to a row, since only
the row's children would be invalidated, and the table's children would remain untouched.

The latter seems more accurate to what that method does, since we don't necessarily
forward that event to the OS, but might instead use it to update cached properties.

For OOP iframe documents, we can't support NODE_CHILD_OF in the usual way, since the iframe resides in a different process.
Previously, we incorrectly returned the application accessible.
This was breaking focus ancestry walking for JAWS.
Instead, don't expose NODE_CHILD_OF at all in this case.
This is fine because the client will then request the parent instead, which will be correctly handled by platform/AccessibleOrProxy code.

For OOP iframes, the top level document lives in a different process.
Previously, we incorrectly returned the top level document in the same process.
This was causing JAWS to incorrectly identify OOP iframe documents as separate tab documents.
To fix this, we must send the real top level document down from the parent process and return that when requested in the content process.

D67954 starts using shadow DOM for menulist and slots the menulist children. This causes GetFlattenedTreeParent to return the slot instead of the parent menulist. This patch fixes it.

Not sure how this could happen, but perhaps the tab is already focused so waiting
for a focus change event causes a timeout.

Having this kind of method will let us know what the states of interest are.
If all the states are cached we can return them without inquiring the full state.

In this patch set I'll introduce state caching, so I thought it's a good idea
to first add a bunch of tests to features that will be touched.

When checking if a parent of a table row counts for a table, take into account that a table might be an ARIAGridAccessible, which remains a generic hyperText, but is still a valid table. Tables with display: block; are such candidates.

This wasn't useful cross-platform.
ATK was the only consumer of this and it now uses ProxyAccessible::ChildAtPoint.
This also means the related aNeedsScreenCoords functionality in PDocAccessible::AccessibleAtPoint is no longer needed and has thus been removed.
Finally, this renames PDocAccessible::AccessibleAtPoint to PDocAccessible::ChildAtPoint for consistency with Accessible::ChildAtPoint now that the functionality is mirrored.

This changes the ATK code to use AccessibleOrProxy::ChildAtPoint, since that already handles walking into OuterDocAccessibles appropriately.
Previously, atk_component_ref_accessible_at_point didn't work at all on OuterDocAccessibles.
Also, for ProxyAccessibles, we no longer adjust the coordinates for ATK_XY_WINDOW in the content process, as this depends on stuff that doesn't exist cross-platform and thus can't be used with AccessibleOrProxy.
Instead, we now handle this in the parent process before making the IPC call.
