Razvan Litianu can you take a look to this one?

Some findings:

• When the expiration date field is updated after being autofilled, and the form is submitted, regardless of the new expiration date, the old value is read back into the client (hence why the “update” card does not display). So the problem seems to be in the content script reading back in the update field data

• This issue seems to only occur when modifying the expiration date field after it has been autofilled (everything works fine when changing the cardholder name field after autofilling)

  • Everything also works fine if the credit card details are entered in manually

• This issue seems to only occur when the expiration date field is a text field. Things seem to work as expected when the expiration date is controlled by dropdowns

The payload (WKScriptMessage) seems to contain old field values (from autofill). Issam Mani could this be an content script issue?

Ok I think this is already tracked somewhere else. Norberto Andres Furlan what do you think is the best way to track these things, so we don’t end up investigating them twice ?

I documented what happens in this comment ( https://bugzilla.mozilla.org/show_bug.cgi?id=1896494#c1 ). TL;DR we have hidden fields and we fill those and this causes the issue. This could happen for any split field not only expiration date.
