Another example is freepeople, shipping address, street address.

also zip for etsy.

 Issue 866075  has been merged into this issue.

etsy and freepeople are of another nature. The problem is most probably rooted in the dynamic form. Added them to crbug/850231.

[Autofill] Keeping the user edit.

Problem:
When we Autofill, to decide if we should fill a field or leave it as
is, we check if the last edit was user's edit. If so, we would not
autofill (clear, etc). But sometimes, the website writes on the top
of the autofilled value (exp: formatting a phone number). So, if the
user adds a value on the field, the JS would edit it, and it would be
overwritten by autofill.
Solution:
Instead of looking at the last edit, look if the user has
ever edited that field.
