Bug 69562 - AccessibilityImageMapLink holds onto it's parent even after it's been freed https://bugs.webkit.org/show_bug.cgi?id=69562 Source/WebCore: Some fake objects, like AXImageMapLink, have weak references to their parent's (since they are fake objects and need some connection to the parent). However, if the parent disappears before the child, then we're left with a out of date reference to that parent. The fix is to allow these elements to clear their parentage when the parent goes away.
