Hardware pause button doesn't work for Chrome media

Similar to (but opposite of) Pause button started working for Chrome / Youtube, messing with audio player controls, I can't get the touch bar Play/Pause button to play or pause Youtube videos in Chrome.

I checked that chrome://flags/#hardware-media-key-handling was enabled.

When I manually play or pause the video in the browser it changes the touch bar icon between playing and paused, but tapping the icon doesn't do anything.

How can I get the media key to control Chrome?

If you have the Google Play Music extension installed, uninstall it. The touch bar play pause button works correctly after that.
