#7337 does a similar thing and has a test, but there was a discussion that was the wrong approach.
Have you saw that?

@JoakimKLarsson thanks for contributing!

I think instead of removing/adding classes like in #7337 one could just remove the focus / add the focus to the button, right? I gave this a quick test and just canceling the enter press is not enough.

Superseded by #12839. However we do appreciate your contributions @JoakimKLarsson a lot and hope to see you send more PR's to address other issues 👍
