As far as I can tell, it works now? I tried vimeo, but if you have suggestions
for other Flash video sites, please let me know.

Pepper flash doesn't supported the windowed mode I think.

Right, Pepper is essentially a mix of windowed and windowless, taking the best
of both. Anyway, I'm pretty sure we made sure that Pepper Flash wasn't subject
to this sort of ordering constraints. NPP_SetWindow was pretty critical for a
bunch of things in NPAPI, but the equivalent (PPP_Instance.DidChangeView) is
only relevant for display.
