"Priority sorter plugin" not configurable any more.
- The configuration page is messed up (see screenshot)
- "Save" doesn't work
(This is the definitive killer)
- "Delete" and "Add" buttons don't work
- While I can change the content of text boxes or drop-down lists
- Most probably due to <table> to <div> in Jenkins 2.277.1
(We jumped from 2.263.4 to 2.277.4, so I can't prove for LTS releases in between)
