I have a repeatable group set up, and after adding a number of items, I can't delete the last remaining item. After I delete the second to last item, the remove buttons on the last item are disabled. Would it be possible to get an update to allow deleting all items?

I'm using the latest public version, but noticed the trunk version's remove function only checks for # of groups > 1 in the JS as well. https://github.com/WebDevStudios/CMB2/blob/trunk/js/cmb2.js#L552
