@geido thanks for the quick fix!
one more ask, when user is deleting search input, they should get a list of increasing options. can you add that functionality to search? we are using it in the Datapanel search as well.

@geido let's open a new PR to implement the enhancement on search! many thanks for fixing this P0 issue!!!

FYI @eschutho @betodealmeida this issue is likely caused by #12006
