Cannot name new playlists

How to repro
M -> Song -> Add Song -> To new playlist
In the popup the highlighted Unnamed is supposed to be a text field. Backspace works, but can't actually type stuff

this is probably 'caused' by: Fix some keypresses registering twice #782 from 2024.1.0 but apparently this screen slipped through.

in the meantime as a workaround, you can create an empty file <playlist name>.upl in the playlists directory before starting USDX, then you can just add it to the existing playlist
