Steps to reproduce

1. Reach the payment form on www.lego.com
2. Click on the expiry date field and select any entry from the CC dropdown.

4. Click on the Card Number field and select any entry from the CC dropdown.
5. Click on the expiry date field
6. Click on the Card Number field again and select clear autofill form.

Expected result

1. All the CC eligible fields should be highlighted and autofilled.
2. The clear form dropdown should be displayed for all autofilled fields.
3. All the CC already autofilled fields should be cleared upon selecting clear form option.

Actual result

1. By selecting a CC entry from the expiry date field will autofill only the expiry date field.
2. The clear form dropdown is not displayed for expiry date field if the fields were autofilled from the Card Number field.
3. By selecting clear form option from the Card Number field will clear only the Card Number field.

Regression range

• Not a recent regression.

Additional notes

• Preview is also reproducible in Chrome but the autofill and highlight are working for both fields. The clear form dropdown is displayed only for the expiry date field there.

:ailea, if you think that's a regression, could you try to find a regression range using for example mozregression?

Re-tested in Nightly 139.0a1 and the autocomplete dropdown is no longer displayed for the Card number field and it is also not autofilled by trigger the autofill from the Expiry date field.
