Affected version:

Fx80 and FX81 - if CC specific prefs are enabled

Tested on:

Windows 10

Steps to reproduce:

1. Have 1 CC profile saved
2. Reach the payment form for https://www.wayfair.com/
3. Click on the "Card Number" field from the Payment section and select any entry from the autofill dropdown.

Expected Result:

Expiry Date should be correctly auto-filled and the user should be able to select another credit card from the drop down.

Actual Result:

Expiry Date is incorrect auto-filled. If the credit card expiration date is e.g 03/2024 the expiration date auto-filled is 20/24 instead of 03/24. After the expiration date is incorrectly auto-filled the user can not select another credit card from the CC drop-down.

Suggesting S2 severity even if this site is P3 priority given CC autofill dropdown malfunctions after autofilling the fields once and expiry date is not correctly filled.

Several other issues observed:

• lack of Clear Form functionality on all fields
• autofill preview is not displayed
• autofill highlight is missing

The issues mentioned in comment 2 occurs also in latest Nightly 85.0a1 (build id: 20201118215158) on wayfair.ca as well. Updating the flags and summary.
