+ AX: CrashTracer: com.apple.WebKit.WebContent at com.apple.WebCore: WebCore::AccessibilityTable::tableElement const + 116
+ https://bugs.webkit.org/show_bug.cgi?id=150349
+
+ Reviewed by Brent Fulgham.
+
+ The crash point for this bug says that the parentElement of the firstBody is garbage when it's accessed.
+ Unfortunately, I could not reproduce this in-situ or with a test.
+ So my speculative solution is to recalculate those body elements to ensure that they're valid before we access.
