Steps to reproduce:
1. Open attached project.
2. Select "Cube" in the scene
3. Try moving slider from left to right in the inspector tab
- Slider becomes glitchy, the value becomes "Nan".

Actual result: setting one of the slider's value to infinity makes slider glitchy.
Expected result: Unity should not let set slider value to infinity or set.
