This issue is fixed only by setting the extensions.formautofill.heuristics.autofillSameOriginWithTop to True. With the pref mentioned above used by default(False), the issue is still reproducible as in the description. Expiration date field is in the main frame and the card Number field is part of cross origin iframe (different from the main frame origin).

Fixed by bug 1916606. The Exp field field that is located in the main frame, is now autofilled and cleared accordingly.
As we agreed with the engineering team and based on this comment, I will mark this as fixed and verified.
