Project Member Reported by w...@chromium.org, Sep 3 2016

Issue description

I hit this on an Android tablet by entering fullscreen on a youtube video while simultaneously hitting the reload button. I was following the repro steps in this bug: https://bugs.chromium.org/p/chromium/issues/detail?id=623536

The stacktrace looks like:
