What did you do?

1. Open the nightly demo page
2. Run document.querySelector('video').defaultPlaybackRate = 1.5; document.querySelector('video').playbackRate = 1.5 in the dev tools
3. Click on any of the test assets
4. Try selecting 1x in the playback rate menu

What did you expect to happen?

It to switch to 1x and the UI to update to reflect that.

What actually happened?

It stayed at 1.5x, other playback rates can still be selected from the playback rate menu, only 1x is the problem.

Are you planning send a PR to fix it?
