SUMMARY
I have a 2 year old plasma5 system where this is also the case, so seems this has "always" been there. I guess next to nobody uses these things maximized on the desktop? 

STEPS TO REPRODUCE
1. Add audio volume plasmoid on desktop.
2. Resize it such that it's not just an icon, but actually shows a detailed view of all the audio devices.
3. Press the hamburger menu on the right of one of the audio devices (to switch between e.g. "Audio Stereo" and "Audio Stereo + Mono Input"

OBSERVED RESULT
Plasmoid interprets the click on the hamburger menu as a long press on the plasmoid itself, which:
1. Hides the hamburger context menu (so I can't actually change the config of an audio device this way)
2. Makes the plasmoid enter "editing mode": resizing dots show up, etc.


EXPECTED RESULT
Hamburger menu just works, I get the option to pick a different device config.
