Description Matthew Cohen 2021-06-16 18:11:12 UTC 
SUMMARY

When running 5.22.1 in Wayland, starting Firefox (with MOZ_ENABLE_WAYLAND=1 environmental variable) leads to the Firefox icon appearing in the task manager, then disappearing. The window is still open, but the icon is not visible in the task manager. I have not had this problem with other programs, and under X11, I get the intended behavior of the icon in the task manager.
 

STEPS TO REPRODUCE
1. Start a Plasma Wayland session
2. Enable Firefox to use Wayland
3. 

OBSERVED RESULT

The Firefox icon disappears from the task manager.

EXPECTED RESULT

The Firefox icon remains, along with icons of other programs.

SOFTWARE/OS VERSIONS

KDE Plasma Version: 5.22.1 
KDE Frameworks Version: 5.83.0
Qt Version: 5.15.2

Weird, works for me with Firefox's wayland support.
Comment 2 Matthew Cohen 2021-06-17 20:25:01 UTC 
Thanks for commenting! I deleted my entire Firefox profile and the icon appears in the task manager as intended. Not sure what happened, but it's not a bug with Plasma.
