Sometimes it even can be scrolled back upon hiding.

Steps to reproduce:
1. Start Kirigami Gallery and select 'Button' widget
2. Press 'Action' button.
3. Scroll past the end of unfolded widget.
4. Without waiting of unfold widget's hiding animation to end - scroll in opposite direction.

Actual result:
Unfold widget is flickering.

simplify wheel management

on some systems (directly libinput, on wayland and newer distros)
touchpads always only set wheel.angleDelta with weird values,
so it must be managed as it was a pixel value
