AX: WebProcess at com.apple.WebCore: WebCore::AXObjectCache::rootObject + 27
https://bugs.webkit.org/show_bug.cgi?id=120434
Reviewed by Darin Adler.
Crash logs indicate that there's a null pointer access in rootObject. That seems like it could only
happen in Document was null.
Unfortunately, there are no reproducible steps and no other information to construct a test case.
