Bug 391117

Keyboard set with French local (fr_FR.UTF-8)

The application window minimize or maximize (toggle) when I press the '^'/'¨' key. 
This is possible to get the character when spamming the key several times.
Spamming the '^' key and press another key after that, can trigger the minimizing/maximazing event as well.
Consequently, this is quite difficult to write accent character such as 'ê'.

After some tries I get this beavior when I press several times the '^' key:
1st time: the application window is minimized
2nd time: nothing
3rd time: the application window is maximized
4th time: nothing
5th time: the application window is minimized
6th time: nothing
7th time: the application window is maximized (note: if I press space after this step the character is printed)
8th time: the character '^' is printed

This process is repeated endlessly if I spam the key.

This key works perfectly using plasma 5 with X11 or on another Desktop Environment using Wayland.
