I tested this braintree example https://codepen.io/braintree/pen/zeamxM that using restricted-input package for expiration date, I'm doing next steps to reproduce:

1. touch expiration date field and enter numbers "222" (so they appear as "02 / 22")
2. touch credit card number field and autofill with saved card number
3. touch expiration date field again
4. touch card number field
5. finally touch expiration date and it become "00 / 222"

I'm not sure yet, but I think this is more likely an issue with the hosted fields code (which handles autofilling behavior accross the iframes) in the Braintree SDK rather than restricted input. I'll do a little investigating to be certain.
