This happened during a media test, but the stack trace is inside nsDisplayList::BuildLayers, so maybe it's more to do with painting. WDYT Matt?

Crash is here: https://searchfox.org/mozilla-central/source/layout/painting/FrameLayerBuilder.cpp#2092 Disconnected() implies that mLayer is nullptr, which is why we're crashing. Probably should check that first.
