When I drag an app icon to the panel (from the application launcher menu or krunner) to the right of the task manager, it looks like it's going to be added there (the existing icons move to make space for the new one), then once I "drop" it / release the mouse button, it's added to the left of the task manager. This with git master including https://invent.kde.org/plasma/plasma-desktop/-/commit/38bf92fc70e6717fd46fb63fc59fc1eb32c721ce.
Do you have the fix for Bug 454105 already?
Yes.
Can reproduce. Might be fixed by one of the panel MRs that are still floating around in review.
