Right, but this test basically means you can't ever remove a character if it was ever present. I was assuming that you still want to remove it (for some reason) and wondering how to safely test the change.

You create two keyboards and use them both and test them separately. Then you create a keyboard update flow. And you test that. Then you make sure you test that the old keyboard shows until the user changes their password.
