1. Reach the Address form on https://www.saje.com/
2. Hover over any saved address entry and observe the autofill preview behavior
3. Select any saved address entry
4. Click on any field and select Clear form
5. Select once again any saved address entry

Expected result

• All the fields should be auto-filled with accurate data.

Actual result

• Postal Code field is not auto-filled correctly, a digit is missing and an error warning for invalid code is triggered; I can reproduce it only intermittently.
• If attempting to auto-filled the address form once again after a Clear Form was previously performed, The Province/Territory field remains empty.

Regression range

• Not a recent regression.

Additional notes

• I can reproduce the behavior for the Postal Code field on Chrome as well.

The City, Province/Territory and Postal Code fields are not auto-filled. Also, the autofill dropdown is not displayed for the mentioned fields.

The same behavior as described in comment 1 is still present in the latest Nightly 116.0a1 (2023-06-19).

This is no longer a valid bug, since the address form for saje.ca has been changed in the meantime and the autofill is working ok there. However there is an issue related to the capture doorhanger, that has been logged here: https://bugzilla.mozilla.org/show_bug.cgi?id=1951890
