Not sure if this is intended… but when you search the stash, only items are highlighted that meet the criteria. If you press Sort afterwards, the stash is sorted and everything becomes highlighted again as if search is nothing functioning. You then can delete or add another character to the search and the search feature starts working again.
- Search in a tab that has at least some invalid results.
- Press Sort
- All items are highlighted.
- Change any character in search to see functionality restored.
