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

			p_screen = get_primary_screen();
		} break;
		case SCREEN_OF_MAIN_WINDOW: {
			p_screen = window_get_current_screen(MAIN_WINDOW_ID);
