### Issue description

This warning gets spammed when scrolling any slider on the color picker of the editor using the mouse wheel.
The value of the slider gets affected nevertheless
```
scene/gui/control.cpp:2012 - This control can't grab focus. Use set_focus_mode() to allow a control to get focus.
```

For example having a script that exports a color
and scrolling the A slider in the Inspector
```
@export var color : Color
```
