Description Finley Watson 2024-07-17 13:28:51 UTC

SUMMARY
Kate's diff feature scrolls two files up and down together (when they are long enough). The text and scrollbar areas scrolls them up and down when the mouse is hovered over them and the mouse wheel is used, but scrolling while the mouse hovers over the line numbering areas does not work.

STEPS TO REPRODUCE
1. Open two files in Kate
2. Right-click a tab and select "Compare with Active Document"
3. View the resulting diff
4. Hover mouse over the line numbers on the left & in the centre of the screen, and try to scroll

OBSERVED RESULT
No scroll

EXPECTED RESULT
Scroll
