Confusing (broken?) state after hitting enter in explorer filter

Describe the bug
Stuck in confusing seemingly broken state after hitting enter after a filter in the explorer view.

To Reproduce

1. begin filter in explorer view by typing / while explorer is focussed
2. typing a search query e.g. test
3. hitting enter leaves the explorer in a greyed out state
4. I seem to only be able to exit this greyed out state by repeating enter, which leaves me editing the name of that file, then I hit enter again to be back in normal focus of the explorer.

Please see the attached demonstration.mov
Expected behavior
My expectation coming as a vim user is:

1. type / to begin filter
2. type in the search
3. hit enter and I'm in the mode where n goes to the next selection as in vim's (:help /)

Additional context
Add any other context about the problem here.

Start by reproducing the issue in the explorer view using the filter steps described, then trace how Enter is handled after entering a search. Confirm that Enter leaves the explorer in the expected navigation mode, where n selects the next match, rather than a greyed-out or file-renaming state.
