F35 to F36 loses German keys

I recently upgraded from F35 to F36 and just noticed that two of the keys aren’t working properly. The upper far left and far right. The upper far left has the degree symbol (which works correctly with the shift key) and below it is the circumflex (caret or in latex \hat) which usually works by pressing it, and then the space bar (or whatever letter should get a circumflex.)

Similarly, the far right key with the two slanted quotes don’t work as a press and then spacebar (when they applied as accents to the appropriate letter.)

All the other German keys seem to work fine: öäüß@µ

Keyboard setup in Generic 104-key PC with

localectl status
   System Locale: LANG=en_US.UTF-8
       VC Keymap: de
      X11 Layout: de

so I’m really confused as to why that would break with the F36 upgrade.

Any tips on how to get those keys to work again?

There’s a bug reported for it already.
