It's not clear to me why this is being removed. Is this a whoops or is this not
wanted anymore?

It's unwanted and is actually causing the button to not work with 'enter' (it
exists from when we were focusing the entire item). I can remove it separately
if you prefer. I just happened to notice it while testing the rest of this
change.

It's good. I just wanted to ask in case it was a whoops.
