Panel 2.5.5 Sort images with drag and drop

Has anyone else experienced an issue in the panel since 2.5.5 while sorting images with drag and drop?
With version 2.5.2 everything works fine, after the update on some of my projects it is not possible to drag the items in the file overview. (Switching back to 2.5.2 it works again.)

I tried to deactivate plugins, etc. and get no errors in JS browser console. Had no luck to find the reason, yet.

Ahh, a break always helps. Found a typo in the blueprint for the sortable file setting. :man_facepalming:
Looks like 2.5.5. is thankfully more strict.
