How to reproduce:
1. Create a new 2D Project
2. In the Hierarchy, right-click -> 2D Object -> Sprite Mask
3. In the Inspector, navigate to the "Sprite Mask" Component
4. Go to the "Alpha Cutoff" and change the value by dragging the name of the variable
5. Observe the results

Expected results: The dragging has enough sensitivity to go through values
Actual results: The dragging is too sensitive making it hard to adjust the value
