Description John Horne 2021-05-15 21:55:05 UTC 
SUMMARY

The maximise button on windows has been configured to vertically maximise when the mouse middle-click button is pressed on the maximise button, and horizontally maximise when the mouse right button is clicked.
This worked fine under X11, but does nothing under wayland.
Tried using the mouse buttons on konsole, (gnome) evolution, firefox etc.


STEPS TO REPRODUCE
1. Configure mouse buttons to vertically/horizontally maximise when clicked on the window maximise button. Go to System Settings, then 'Window Management -> Window Behaviour -> (tab) Titlebar Actions'. Save the settings.

2. Open 'konsole', and test using the buttons.
3. 

OBSERVED RESULT
Nothing happens.

EXPECTED RESULT
The window should vertically or horizontally maximise depending on the mouse button pressed.
