Comment (by joedolson):

 I'm going to say it was an oversight; the code got removed along with the
 changes to section titles, but shouldn't have been.

 I've added a PR to fix this. The changes in PR 8398 would work to restore
 the focusability, but would also mean that the button was focusable when
 it's supposed to be hidden; the `tabindex="-1"` is there so that the back
 button can't receive focus when it isn't visible.
