SUMMARY
I wanted to try the new SSH bookmark plugin thingy, but if I click on the "Plugins" menu, it does nothing.

STEPS TO REPRODUCE
1. Open Konsole from Plasma app menu;
2. Click on "Plugins"

OBSERVED RESULT
The focus remains exclusively on the "Plugins" menu, and hovering on the tool buttons (the ones that build a predefined layout) does nothing instead of coloring their outlines. Pressing ESC fixes this (or clicking anywhere else).

It's like whatever is supposed to be painted/shown, is not but the app think it is.

EXPECTED RESULT
The plugins settings/tab should open.
