SUMMARY
If the focus is on the last item in a sidebar, pressing the down arrow causes the items to become vertically aligned to the bottom

STEPS TO REPRODUCE
1. Go to System Settings > Workspace > Startup and shutdown
2. Click in the sidebar that shows subcategories, placing the focus on the last item (Desktop session)
3. Press down arrow (keyboard key)

OBSERVED RESULTS
Pressing 'down' when the last item in a sidebar is selected vertically aligns everything to the bottom (see attached screenshot).

EXPECTED RESULTS
Pressing the down arrow in step 3 should do nothing.

lol oops
Comment 2 Nate Graham 2021-07-30 16:03:59 UTC 
This appears to be a defect in Kirigami.ScrollablePage. I can reproduce the issue with other UI elements based on it what are not tall enough to be scrollable. Will investigate.

[ScrollView] Don't scroll with arrow keys if the view isn't scrollable

Otherwise, a non-scrollable view will oddly teleport its contents to the
bottom when you hit the down arrow key.
