A few issues I couldn't resolve:
1. I don't have enough expertise here to know if "data:" is a proper signon
realm...I just went off what the WebPasswordForm had.
2. I couldn't get password_form->submit_element to be filled in in spit of
including the submit element in the HTML.
3. password_form->origin ends up just being the HTML itself.

I also don't know; but if it seems to work, then that should be fine.
This might be because the submit element comes before the password, which is
rather unusual.  Anyway, it's probably not a particularly big deal for this
test.
Again, this doesn't seem like a big deal for this test.
