Is there anything we do inside setVideoLayerFrame() which assumes it's being run on the web thread?

You can just do: 

FloatRect videoLayerFrame = FloatRect(FloatPoint(), videoElementClientRect.size());  

Or use constructor syntax rather than assignment. FloatSize is constructible from an IntSize (but not vice-versa).

Maybe. Just to be base I'll move the operations that need to be sync'd into the web thread instead of into the UIThread.

I thought there had to be something more succinct.
