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

N/A 
k->set_key_label(fix_key_label(keysym[0], keycode));

						k->set_key_label(keycode);

					if (keypress) {
						k->set_unicode(fix_unicode(tmp[i]));
					}
					k->set_echo(false);
					if (k->get_keycode() == Key::BACKTAB) {
						
						k->set_keycode(Key::TAB);
						k->set_physical_keycode(Key::TAB);
						k->set_shift_pressed(true);
					}
					Input::get_singleton()->parse_input_event(k);
