Steps to reproduce
Press Ctrl+F*, enter a search term which will generate more results than will fit on one screen, press either Shift+Enter* (Flat seach) or Ctrl+Enter* (Search in all documents).
(* assuming default keyboard shortcuts)
I expect to be able to scroll the page of search results, using any combination of scroll wheel, a scroll bar, or keyboard shortcuts (arrows, PgDn, etc.)
No scroll bar is visible and neither scroll wheel (or in my case, trackpad equivalent) nor keyboard shortcuts allow scrolling. So only the first page of results is accessible.
