Steps to repro:
1. Create a new HDRP project
2. Project view > Right-Click > Create > Visual Effects > Visual Effect Graph.
3. Visual Effect Graph > Add Node Operator > Logic > Probability Sampling.
4. Probability Sampling > click on settings icon > Minimise Dropdown.
5. Change multiple properties(ex.Colour, AnimationCurve, bool...) and observe

Actual Result:
Multiple Properties are getting clipped on minimising probability sampling logic node dropdown

Expected Result:
Probability sampling logic node dropdown should minimise fairly without clipping any properties
