Godot keeps clicking out of the color editor

EDIT: I did a test it seems to be single window mode

### Steps to reproduce

Go in editor settings and search for single window mode 

Enable it

Try using the color editor on any color field with single window mode

### Minimal reproduction project

		xkeysym -= ('a' - 'A');
	}
	Key key = KeyMappingX11::get_keycode(xkeysym);
	
	
	if (key == Key::NONE) {
		return p_keycode;
