This is another bug where I don't see the webgl.out-of-process pref set, but we're clearly in the out-of-process branch. I'm somewhat suspecting that maybe the crash reporter isn't seeing the up-to-date pref settings.

Assuming we're here because of webgl.out-of-process:true, this is expected behavior, and this is RESOLVED INVALID.
