SUMMARY
When user mouse right click on any icon of "Quick launcher" widget, it shows (as it should) a contextual menu BUT Plasma seems to think user want to MOVE the icon-launcher where user did the mouse right click and any movement of mouse, will move that "icon-launcher" from original place.


STEPS TO REPRODUCE
1. Click on any application icon showed in "Quick launcher" widget
2. Move mouse


OBSERVED RESULT
- The clicked icon begins to move from original position
- Moving mouse pointer over contextual menu showed don't show options as "clickable"

EXPECTED RESULT
- To not consider user want to move icon (that function is "left click and drag")
- To show highlighted options from context menu when user moves mouse over them
