For some reason, when I try to autofill with stored credit card information, Firefox (99.0.1) fills the form with credit card number and expiration date when I mouse over a credit card choice, and then when I actually make the choice, the entry gets erased.

I have checked, per an earlier (now archived) question, and there is no "autocomplete off" (or any mention of "autocomplete") in the web page in question.
