Should we also take the `autocomplete` attribute into consideration here? If so,
we could pick up "username", for instance.

I thought about it a bit, and I would say that not just yet. I'll keep it in
mind for future iterations :)

We could define InputFieldTypeUsername and show some special context menu item
on fields with autocomplete="username". However, then we'll also want the same
behavior for forms that do not use autocomplete. We could say that if no field
in the form has autocomplete="username", then all of them will be treated as
InputFieldTypeUsername.

This might be useful, but it seems like inconsistently rewriting the password
manager heuristics in blink, and I would avoid it until we have clear idea what
exactly we want to offer for the username field. The current design expects no
action on the username field; the username value will be found using the usual
heuristics.

About autocomplete="current-password" and "new-password", I had a quick chat
with Václav and we arrived to the conclusion that we don't want to discriminate;
the user using the force-save feature knows what they're doing, and they should
decide which password field is correct themselves.
