Can't modify PolygonLabels

[johan-sightic]

Describe the bug
If I create a PolygonLabels annotation or get one from a pre-annotation model I can not modify it afterwards. Sometimes i find a magic combination of clicks that allow me to modify it but it is very unreliable. Regular Polygon annotations and other annotation types can be modified just fine.

To Reproduce
Steps to reproduce the behavior:

1. Create a PolygonLabels annotation
2. Submit annotation
3. Select annotation from the list on the right
4. Try to modify it
5. Nothing happens...

Expected behavior
PolygonLabels annotations should be modified just like other annotations.

Environment (please complete the following information):

• OS: Ubuntu 24
• Label Studio Version: 1.15.0
• Browser: Google Chrome, Firefox

Additional context
I think these issues are about the same problem but none of them has any replies from a dev:

• Cannot return to drawing Polygons after panning Image. #5727
• "Move" mode cannot be deactivated #4359
• Clicking onto pane disallows readjusting of PolygonLabels  #5626

Hello,

Can you try these suggestions as a workaround?

• Reselect by Vertex: After selecting the annotation from the list, try clicking directly on one of the polygon’s vertices. This can sometimes “unlock” the polygon for editing.
• Tool State Check: Ensure that no other tool (like pan or move) is active when you try to edit. For panning, consider using shift+drag rather than the dedicated pan tool.
• Browser Console: Look in your browser console for any errors when you try to activate polygon editing, as that might help us narrow down the issue.

Thank you,
Abu
