SUMMARY The button to change the system panel back to maximized does nothing, so a change to a floating panel is irreversible. STEPS TO REPRODUCE 1. Go into edit mode on the panel 2. Click "More options" 3. Click "Floating panel" 4. The panel is now floating. Click "Maximize panel" OBSERVED RESULT The panel remains floating, and the "Floating panel" option remains highlighted. EXPECTED RESULT The panel would change from floating to maximized. SOFTWARE/OS VERSIONS Windows: N macOS: N Linux/KDE Plasma: Y (available in About System) KDE Plasma Version: 5.25.3 KDE Frameworks Version: 5.96.0 Qt Version: 5.15.5 ADDITIONAL INFORMATION I am aware that my Plasma is out of date.

Oops! I misunderstood the button functions. All good now :-)
