Steps to reproduce the bug

1. Go to any YouTube video. I specifically tested this with a few random videos from the trending page.
2. Play the video with only background audio.
3. While the video is playing, change the tempo in the playback speed controls option on the top right.

Actual behaviour

The new tempo is not reflected in the playback speed control display from the playback queue unless you scrub around the video's audio or pause.

Expected behavior

The updated playback speed should be reflected immediately after changing the playback speed.

Screenshots/Screen recordings

In the screenshot, the video is playing at about 2x speed. However, the playback speed in the top right still says 0.61x.
