    Description

      The behavior of flickable acceleration changed between 5.15.7 and 5.15.8.
      Does 5.15.8 have an intended behavior or is it a bug?

      Under certain condition, a single click(notch) of the mouse's scroll wheel causes the flickable to scroll much further than anticipated. Usually a single mouse wheel click scrolls by about 5 lines on my machine, but occasionally it scrolls by a much wider distance (e.g. about 30 lines).

      How to reproduce
      1. Use the attached qtbug106338.zip , build and run
      2. Try scrolling down by one notch of the mouse's scroll wheel. It scrolls 5-7 lines
      3. Flick the view to up direction
      4. Try scrolling by one notch. It scrolls about 30 lines ( Expected result : about 5 lines )
