When editing permissions for a user, the search box doesn't work

Overview: When editing permissions for a user, an extra screen opens with search and filter within the permissions. The filters are working, but the search is not

Steps to Reproduce:

1. Log into folio-snapshot.
2. Go to the Users app
3. View details for an existing active user, or create a new user
4. Edit the user to assign permissions to them
5. Type something in the search box (e.g. Agreements)

Expected Results: The list of permissions is narrowed to the ones that contain the word "agreements"

Actual Results: The search is not executed

Additional Information: See attached video

NOTE: This is working fine in Iris Bugfest, so it looks like a regression was introduced some time after that, I think
