FIX: ensures category chooser is working with non english char (PR #10866)

This commit is also moving one test to a component test.

A followup to this commit would be to ensure every dropdowns are using a regex instead of the normalize/lowercase system we have now.


This feels like a hack. Why not just normalize the filter?

how is that a hack ?

Ok I pushed a version applying my normalize function to the filter

Well, it’s not if we want regex search for categories, but if that’s the case then, the commit is misnamed.
