Custom tag search in track browser never yields empty results

Lexicon version: 1.9.5
Operating system: Mac

Bug description
When searching for anything in the track browser custom tag field there will be always all tracks visible. I’d expect to see nothing, just like in the other fields like title or artist.

Step by step to reproduce

  1. Click into custom tag search field
  2. Search for some nonsense
  3. See that all tracks in the current view are still displayed

Thanks!
