AX: changes to WAI-ARIA grid aren't perceived correctly by VoiceOver
https://bugs.webkit.org/show_bug.cgi?id=35514
Reviewed by Darin Adler.
WebCore:
When a table's DOM is changed and an AX Table is not asked first for its children,
it would return wrong information. A table needs to make sure children are up to date in
all methods that can be called from the outside.
