My panel is configured so that it does not take up the whole width of my screen but is instead smack dab in the middle at about half-width. After upgrading to Plasma 6, I noticed that the Application Launcher menu is middle-aligned instead of left-aligned like it was before. It now extends past the panel edges and not only looks visually unappealing but also makes 
mouse navigation less optimal than it was before.

STEPS TO REPRODUCE
1. Shrink the default panel so that it does not take up the full width of the screen
2. Click on the application launcher

OBSERVED RESULT
Application launcher menu is middle-aligned with the launcher button

EXPECTED RESULT
Launcher menu should be left-aligned so that it doesn't extend past the panel edges.
