This change messes with anchor links. It obscures the item being linked to.
I don't see a way around it. Undoing for now.

      Fixes issue 4071.

      ??? original CL description
      doc css: topbar sticks to the top of large windows.
      Rationale: for large screens, the convenience of not having to scroll
      to the top of the page to do a search outweighs having less vertical
      space.
      Tested with Chrome, Firefox, Safari with various window and text sizes.
