Open the system tray configuration dialog, go to the "Entries" tab, and click OK without changing anything. The system tray will now be in a broken state: - Clicking the pop-up arrow twice doesn't close the popup. - The application icons (kmail, choqok) stop changing between active/inactive when required. This persists until plasmashell is restarted.
Please include Qt/Frameworks versions
Qt 5.11.1, Frameworks 5.50
Also reproducible in 5.13.5 (I don't open the configuration dialog much so I didn't notice until I started playing with the beta)

Popup also doesn't close on Wayland Operating System: KDE neon Developer Edition KDE Plasma Version: 5.14.80 Qt Version: 5.11.1 KDE Frameworks Version: 5.51.0 Kernel Version: 4.15.0-34-generic
Seems to be the same, yes, although I don't need to change anything in the dialog for it to break.
