I think this is still the issue. In particular, we rely on style resolution to find fonts in use. So if there was no style resolution by the time Document::implicitClose() is called, then we may fail to detect any fonts available in the document.

The reason this is flaky in Safari is probably because Safari injects scripts to run the reader availability and other things so it's probably triggering a style resolution before load event is fired in some cases.
