Looks like a nice simplification but iOS sim is not happy.
Let's rerun the test to see whether these were flaky failures.

We could inline it in the header file.

Indentation is not correct.

Unneeded.

This is hit now by the iOSsim bot.

Just realized a problem here. With this change, some layout tests may send requests to change presentation mode before the transition is done. Unfortunately, those requests will be ignore by the video element and then end with a test failure/timeout.

Nit. The space is not needed here.

Are we also doing the evangelism side of this to try to get the Akamai script fixed?

I’d like to see a comment documenting a tiny bit about why we need the quirk and predicting/describing when we can remove it. Can likely be a short comment without tons of details, but should not require looking back at the ChangeLog.

Could use _s here to make the AtomString construction slightly more efficient. Or use static const AtomString so we make the atom strings only once the first time this function is called.

Why not have this function take an HTMLVideoElement instead of an HTMLElement? The is<HTMLVideoElement> check seems wasteful.

Great point, changed to use const AtomStrings.
