Add extra classes to results form

These js- prefixed classes should not be necessary for our custom search form. The related JavaScript code from the media library doesn't do anything we need if I'm not mistaken. Could you explain why these classes should be added?

Hello,

They are indeed not needed. But I just wanted to more aligned with the core "media_library" module were they are also added. I noticed they weren't there since our theming didn't work here on the search form. (They are based on the js- classes) But it is indeed a trivial "problem" let's say. Theming can be altered easily

I could agree on closing or committing.
