_docload .html crashes with "Assertion failure: cached Binding == a Proto Binding" on Windows debug
Copy from bug 1383845 comment 8: So at least in accessible/tests/mochitest/events/test_docload.html, it seems the issue is that, cachedBinding uses Servo backend, while aProtoBinding uses Gecko backend, which causes this inconsistency. And in this case, the binding in question is the resizer. For test_docload.html, this is probably because of the "about:" and "about:buildconfig" pages in iframes, which may still using Gecko backend. This is inevitable for now given we don't really want to enable stylo on about pages at the moment (bug 1376805), although I guess "about:" and "about:buildconfig" may actually be fine to use stylo. All reftests and crashtests which have this bug annotated involves some kind of iframe (or frame) with either data URI or operation in empty documents, which, I suspect, should have been fixed in bug 1384162. I have no idea why this happens on Windows only, though. It seems to me this really should be a problem across all platforms.
Why did I file two identical bugs :/
