…emilk#7803) * Closes emilk#7749 ## What In our hit test code we have special handling for thin widgets, to make them easier to hit. The widths of our scroll bars are animated. Together, the heuristic would trigger as the scroll bars were shrinking, leading to the scroll bars being _hovered_ which lead them being too wide, making the heuristic fail, which would again make them shrink, causing the bug. ## Bonus Now the scroll bar is only shown as hovered if the mouse is actually hovering them and nothing else. Previously they would show as long as the cursor were in the general area (but maybe actually hovering something else).

* Added in emilk#5468 * Related to emilk#7803 The code doesn't seem to longer be needed. Interacting with a resize splitter isn't very difficult, and I never liked that special case.

What
In our hit test code we have special handling for thin widgets, to make them easier to hit.
The widths of our scroll bars are animated.
Together, the heuristic would trigger as the scroll bars were shrinking, leading to the scroll bars being hovered which lead them being too wide, making the heuristic fail, which would again make them shrink, causing the bug.
Bonus
Now the scroll bar is only shown as hovered if the mouse is actually hovering them and nothing else. Previously they would show as long as the cursor were in the general area (but maybe actually hovering something else).
