Scrolling in a note when doing a search in it/viewing source code

Whateverr

I often use the search function in a note (not in the whole library) or look at the source code of a note. But when the search/source code windows is open, then I can't scroll anymore in the note. It's a big problem for search as sometimes the highlighted word is almost hidden by the bottom of the note.

Is there a way to enable scrolling in the note while the search/source code window is open?
I guess that it will be done by changing some css/js rules in ressource/tinymce.
Any idea which ones?

Thanks a lot!
