• Not reproducible in Chrome.

On aboutyou.de the highlight problem is reproducible as well, but only for the Expire date fields (tested with Fx 113.0a1 and Fx 111.0.1).

The autofill specific yellow highlight issue is no longer reproducible in Nightly 125.0a1 (2024-03-11). All the CC fields are now highlighted accordingly for both preview and autofill.
As we agreed with the engineering team and based on this comment, we will mark this issue as fixed and verified.
