Touch bar stuck in muse after changing Spotify volume

[msoyland]

I am running Muse on High Sierra. Whenever I change the volume in Spotify by use of the Muse controls, I am unable to close Muse and return to the current app controls. This is because when I leave the volume control interface, the "x" at the left is suddenly replaced with the escape key. I then have to either close Muse entirely or press the keyboard shortcut for invoking the HUD, to regain the current app controls.

Yeah, I know, super annoying. Unfortunately I'm pretty sure it's an issue with High Sierra, as:
1 - I didn't experience this with 10.12
2 - It happens with other apps as well. See here with QuickTime and Xcode.
I think we should open a bug report.

Yeah, we should do that. Hopefully the bug will be quickly fixed.

@xzzz9097 Did you file a bug report? I just tested the latest public beta, and the problem persists.

[msoyland]

Not fixed in the 4th beta either.

Apple Developer Relations contacted me and prompted to test 10.13.2b2, and it seems the issue is finally fixed.
