Use input placeholder to determine correct format for credit card expiration date

Bitwarden often fills credit card expiration dates with the wrong format. I was thinking that maybe reading the placeholders could help find out the right format ? Maybe it already does this, and the issue I have is because the placeholders use French designations (MM/AA) instead of English ones (MM/YY) ?

It’s not very good at this on English sites either. Often the fields are left empty.

I don’t know what the heuristics are, but I’ve noticed that BW is way behind LastPass at getting this right.

Interestingly, I have find that LastPass has often get this wrong as well and I have to manually input it from looking inside the vault.
