[Fixed Bug 2023.4] Options-Graphics-Behavior-Buttons: Values change when click outside area.

DenisFR

When changing Buttons Behaviors, left clicking to Add (or elsewhere) change the value to Left.

The way to add it is using Tab key to select Add then hit space key.

Other things, when using more than one button, value return to one when relaxing other. Like Middle-Right return to Middle when relax right button. The fix is to move the mouse cursor outside the area. Value should change only when button down.
