Editing Lighting Intensity Field Value Fails

You cannot change the intensity by just adding/changing numbers. You have to completely retype the entire value.

Found in 4.21 CL# 4613538 and 4.22 CL# 4681912

1. Open the editor
2. Place a point light into the scene
3. Change the intensity to 300 and press enter
4. Delete just the 3 and change it to 2 so its 200 and press enter

Results:
The value will return to 300

Expected:
The value would change to 200

Workaround:
Delete the entire value before inputting the value you want
