Description David 2021-10-20 01:45:31 UTC 
SUMMARY
If I put a resource usage widget at the right side of my panel, and then right-click to switch alternatives to something else, the widget will be forcibly moved to the left side of the panel.

STEPS TO REPRODUCE
1. Put a disk usage widget or similar next to the system tray (right side of the panel).
2. Right-click the widget, select "Show Alternatives", and switch to some other alternative.

OBSERVED RESULT
The new widget is placed at the left inbetween the application launcher and the desktop pager.

EXPECTED RESULT
Should stay where I put it.

Yes, I can reproduce this. It didn't used to; seems like a regression. Quite annoying.
Comment 2 Felipe Kinoshita 2021-10-21 22:09:58 UTC 
FWIW this also happens to me on 5.22.5

Comment 6 Oleg Solovyov 2022-02-01 14:30:12 UTC 
Fix of this bug causes regression: leftmost widgets are moved to the right.
Comment 7 Oleg Solovyov 2022-02-02 07:58:38 UTC 
UPD:
@ngraham I think your fix was wrong. If widget.width == 0 then widget.x == 0 (QML bug?) and our candidate is inserted after it.

Can you submit a merge request?
