Nice, we got rid of setDisplayMode() entirely.

This seems to have made this test very flaky: imported/w3c/web-platform-tests/html/semantics/embedded-content/the-video-element/intrinsic_sizes.htm
Tracked in Bug 211612.

Is there code that stops the poster loading once we load the first frame?

Not really about this patch:

I wish we had a more consistent rule about when to call through to the base class in parseAttribute functions. If it was up to me, all parseAttribute functions would call through to the base class always, even when they handle the attribute, except when they are trying to disable some specific work the base class does. But it’s more efficient to *not* call through to the base class if you know it has no work to do, so some might prefer our current status quo where we often don’t call through.

Is the idea here that if hasAvailableVideoFrame() is true, the display mode will be changing to Video very soon? Why not change it to Video right now?

Oops indeed, I wonder how I did that!

That is the idea, but I like your suggestion - there is no reason to wait. 

I'll make that change, thanks!
