SUMMARY
If I click the menu of some app, panel widgets like the (official KDE built-in) volume control will not react to mouse scrolls anymore until the menu of the app is closed.

STEPS TO REPRODUCE
1. Put the sound control widget on the panel.
2. Launch Dolphin.
3. Click the hamburger menu in Dolphin.
4. Position the mouse pointer over the sound widget.
5. Move the mouse scroll wheel so as to change the volume.

OBSERVED RESULT
Nothing happens while the hamburger menu is open.

EXPECTED RESULT
Should change the volume.

On X11, this is unfortunately an unfixable quirk of how X11 works: when a menu is open, it blocks other apps from receiving input. This already works properly on Wayland.
