This really shouldn't be possible.
All XUL trees should have nsIDOMXULMultiSelectControlElement, and the tree is focused at this point, so it shouldn't be dying.
Nevertheless, this sometimes happens in the wild and was causing crashes.

Mark the html:mark element to the new ROLE_MARK, which currently maps the same as role_text, and the xml-role of "mark", make sure we expose the roleDescription on Mac, and adjust the test so it tests that the attributes don't pick up any unexpected color for this particular element. So, the background attribute is empty when there is no unexpected, non-default background color.

Previously, we only restored focus within the top level remote browser.
This is fine for remote documents without iframes or only in-process iframes, as was the case with e10s.
For Fission, if an OOP iframe has focus, we need to get the appropriate nested remote browser.
Fortunately, BrowserParent::GetFocused was introduced to do exactly this.

If an embed or object doesn't specify a URL (or specifies a URL which isn't web content), it won't be created as an OuterDocAccessible.
For example, an embed with no src will be created as a generic HyperTextAccessible.
If the URL later changes to refer to web content, we must recreate as an OuterDocAccessible.
Previously, we didn't recreate, which was causing an assertion and may have caused other strange issues as well.

An OuterDoc shouldn't get accessibility focus itself.
Focus should always go to something inside it.
However, OOP iframes will get DOM focus because their content isn't in this process.
We now suppress the OuterDoc focus in this case.
The OOP browser will fire focus for the correct Accessible inside the embedded document.
Without suppression of the OuterDoc focus, the two focus events will race and the OuterDoc focus may override the correct embedded focus for accessibility clients.
Even if they fired in the correct order, clients may report extraneous focus information to the user before reporting the correct focus.

1. When creating a DocAccessibleParent for an embedded document in an OOP iframe, it's possible that the embedder accessible hasn't been set yet.
This can occur if the iframe is initially hidden.
Previously, we incorrectly set the document up as a top level document (e.g. tab document) in this case.
Now, we set up the document as top level in its content process, set up the proxy, etc.
The document will be added to its child document later when the embedder is set.
2. When setting the embedder accessible for an OOP iframe, check if the embedded DocAccessibleParent already exists.
This can happen if an iframe is hidden and then shown or an iframe is reflowed by layout.
If it already exists, add the embedded (child) document to its embedder.
3. Mac's implementation of ProxyCreated requires that AddChildDoc be called *before* ProxyCreated so it can invalidate the native children of the parent.
Because it's possible for an OOP iframe document to be added to its embedder after the document is created, we can't satisfy this requirement for OOP iframe documents.
Therefore, we now allow a null parent in Mac's ProxyCreated and use the reorder event fired later to invalidate the native children.

We noticed a handful of linker errors when building with other build optimization flags -Os, -O2, and -O3 instead the default, -Oz.
(see Bug 1591725).
This change is intended to be 0-impact on functionality -- simply resolving the linker errors.

Sometimes, depending on how children were changed, children might be in the insertion list out of order; e.g. [child2, child1].
It's also possible that an earlier child (child1 in the above example) is being moved out of another container.
When processing the earlier insertion (child2), we'll determine we need to move it within its parent and will fetch its new previous sibling so we can move it into the right place.
However, in this case, the new previous sibling (child1) will be in the wrong container.
We can't move in that case; the new previous sibling's index in parent will obviously be wrong, since it's relative to the wrong container.
Therefore, we just skip the move.
Since the previous sibling (child1) is later in the insertion list, the ordering will be corrected when we process that insertion.

OuterDocAccessible has some special behaviour.
We really shouldn't try to use some other class for iframes.
Anyway, making an iframe part of an ARIA table won't work for other reasons, plus I'm not sure it makes much sense.
