Steps to reproduce:
1. Create new Unity project
2. Open Grid and Snap Settings in the Scene view window
3. In Grid Size > X value enter “NaN”
4. Observe the X, Y, Z fields
5. In Grid Transform > X value enter “NaN”
6. Observe the X, Y, Z fields
Actual results: Entering “NaN” in Grid Transform Position, value goes back to 0, meanwhile entering “NaN” in Grid Size, “NaN” stays in the field
Expected results: Fields in Grid and Snap Settings should work consistently, if Position fields resets to 0, Grid Size and Increment Snap fields should reset to 0
Reproducible with versions: 6000.4.0b12, 6000.5.0a9
Can’t test with versions: 6000.3.9f1 and lower (Grid and Snap Settings not available)
Tested on (OS): macOS Silicon Tahoe 26.3.1 (M1)
