It seems that it was block by Static Type Checking.

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.
sk.track = E->key().track;
		if (selection.has(sk)) {
			continue;

		undo_redo->add_do_method(animation.ptr(), "track_remove_key_at_time", E->key().track, newtime);
		_AnimMoveRestore amr;
		amr.key = animation->track_get_key_value(E->key().track, idx);
		amr.track = E->key().track;
		amr.time = newtime;
		amr.transition = animation->track_get_key_transition(E->key().track, idx);
		to_restore.push_back(amr);
	}
