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

Re-tested in Nightly 140.0a1 (2025-05-12) and the issue is no longer reproducible. The form can be autofilled correctly after clearing the City field using the X option from the field and then clear the form.
