Bug 457159

SUMMARY
I incorrectly filed my last bug and fat fingered the Plasma version I'm on, sorry about that!

There is an issue present since at least 5.24.5 which causes icons pinned to the panel to lose their positions between activities. I have been able to reproduce this behavior as such:

1. Setup two activities with applications pinned to the panel in each activity. It's important to have both distinct and shared pins (e.g. some of the applications are marked "Pin to Task Manager" > "On All Activities").
2. Move around some of the pinned applications on one activity. 
3. Switch to the other activity.

You would expect to not see movement on the activity you did _not_ switch pins on, but instead I'm finding that the applications which are pinned in both activities move around in such a way that they are bunched up. Attached is a video that helps explain.

OBSERVED RESULT
Pinned applications are moved without user interaction

EXPECTED RESULT
Pinned applications are not moved without user interaction.
