Popup menu in system tray opens wrong direction under KDE

[ghost]

Details about the problem

Open the system tray once. Hover over a device, and the menu options will be rendered partially or entirely offscreen.
I am using another monitor to the right, not sure if that affects anything (as it doesn't get rendered past the cutoff).
Also, this seems to fix itself and then consistently break again at startup

Operating System / Desktop Environment / Version(s)

Linux 6.2.11-arch1-1 (64-bit)

KDE Plasma (Wayland) 5.27.4

Affected Devices

N/A (my mouse works fine)

This may also be a good opportunity to mention that the system tray doesn't highlight or checkmark selected settings, which seems like a missed opportunity

Can confirm, it's a bug in KDE. Applications have no control over which direction these menus open:

It's been a bug for as long as I started using KDE daily some years ago. This app currently uses a GTK technology to build the tray icon and intends to move to a Qt implementation in future - although that's not going to fix it either, it seems.

Thanks for the feedback. Maintaining the state has always been a challenge (buggy) for the tray applet, since devices can be changed externally (via Controller, command line or another app). To keep things lightweight, the tray applet opted to be more a "do this", "do that", but it's good to know.
