Log Message:

AX: Children-changed events are not issued when direct children of a canvas
are added or removed, breaking accessibility/dynamically-ignored-canvas.html in
ITM

Reviewed by Joshua Hoffman.
AXObjectCache::childrenChanged(Node&) exited early for anything that had a
renderer under the assumption that we would
get notifications from the render tree for rendered things. But canvas
descendants are not rendered, so that assumption
isn't true in that case. Allow RenderCanvas as an exception in this method,
fixing the test in ITM.
