The user agent does not have to fill in all eligible form controls, and it can fill
+ in form controls that are not eligible. In particular, it can ignore
+ shared-autofill
depending on the type of data
+ to be filled and the relationships of the controls' node navigables. For example:
The user agent can ignore shared-autofill
+ when filling in usernames and passwords which are associated to a specific
+ origin.
The user agent can ignore shared-autofill
+ in Document
s whose navigable is not a descendant
+ of the fully active descendant of a top-level traversible with user attention
+ because payment form controls are frequently hosted in cross-origin iframe
s
+ like in the example above.
+
The user agent can fill in cross-origin form controls because the user + consented.
