Do not fire content mutation event on changes to ns
Canvas Frame's anonymous content
Follow-up for 1110039 comment 52. When running "./mach crashtest layout/base/crashtests/897852.html", we have a issue that the frame tree will be destructed after constructing the first AccessibleCaret. We protected it by adding nsAutoScriptBlocker in AccessibleCaretEventHub::Init(). The full callstack without nsAutoScriptBlocker: https://pastebin.mozilla.org/8832301 roc suggested in bug 1110039 comment 52 that we should fix in a different way --- content mutation event listeners should not fire on changes to the nsCanvasFrame's anonymous content.
Base on comment 1, I'll keep the nsAutoScriptBlocker in AccessibleCaretEventHub::Init() and close this issue.
