Confirmed issue on 2.13.1

Since we're not displaying the actual input field, but rather treating its label as the input, the obvious solution would be to add a tabIndex to the label. This would work, but comes with its own set of issues - on its own, that change would trip up the no-noninteractive-tabindex rule. This could be solved by giving the label a role (say, button), but would then cause another issue by tripping the no-noninteractive-element-to-interactive-role rule. To be honest, I'm not sure the best way to deal with this off hand.
