           Summary: Selected Item in View & Viewport jumps around on
                    Window Resize

           Product: dolphin
           Version: 23.08.3
          Platform: Archlinux

  Target Milestone: ---

SUMMARY
***
When scrolling through a large directory, the file view jumps around on window
resize. If you scroll through 25% or  [ select a photo ] that on window resize
the "seeked" view should remain statically anchored to either the last selected
file or the 25% progress until you use the scroll wheel again to navigate
further ahead.
***

STEPS TO REPRODUCE
1. Have Window Tiling enabled
2. Open dolphin to a ~/Pictures directory with over 200 pictures and have it
maximized to 100% width.
2. Scroll 25% of the way down and click/select a picture.
3. Open a second Dolphin Window, Web Browser / App splitting the windows into
50% width each
4. The view-port jumps from 25% to 50% and the selected item is now 25% behind
the current view.
5. (Optional: Use arrow keys to jump back to the selected item[s])

OBSERVED RESULT
View doesn't remain statically anchored on resize

EXPECTED RESULT
View should remain consistent and static. Perhaps a setting / option to anchor
to "last selected item" or "active scroll progress"
