SUMMARY
I've just installed Plasma 6 beta and set my panel to "fit content" and "center" alignment (to act as a dock). If you click the Kickoff button, it will try to center the application launcher on the Kickoff button (see attached image).

When the panel is set like a dock, the application launcher should be either: (i) left aligned with the kickoff button or (ii) centered on the screen.

I believe the "Configure application launcher" dialog should have an option about that.

STEPS TO REPRODUCE
1. Set the panel to "fit content" and "center" alignment
2. Click the Kickoff button
3. Notice the problem as described above (and depicted in the attached image)

OBSERVED RESULT
The app launcher tries to center itself on the Kickoff button.

EXPECTED RESULT
The app launcher should either be left-aligned or centered on the screen (ideally this should be configurable).
