If it's right.

Why it doesn't just disable other option except for String and StringName?

### Steps to reproduce

1. first select string type
2. input a text
3. change type
4. change back to string  -- it don't work
5. change to stringname -- it works
6. change back to string -- it works

### Minimal reproduction project

I think it don't need reproduction project.

		return;

	float anim_step = animation->get_step();
	if (anim_step == 0) {

	if (p_from_mouse_event && Input::get_singleton()->is_key_pressed(Key::SHIFT)) {
		
		
		
		
		anim_step *= 0.25;
	}
	float pos = timeline->get_play_position();
	pos = Math::snapped(pos + anim_step, anim_step);
	if (pos > animation->get_length()) {
		pos = animation->get_length();
	}
	set_anim_pos(pos);
	emit_signal(SNAME("timeline_changed"), pos, true, p_timeline_only);
