    Make password autofill compatible with Angular forms
    
    Honestly, I have no clue what I've done here, but it's what Chromium
    does when it autofills a form, and it makes an Angular password form
    work on one of our internal sites, so it's probably good right?
    
    This is a squash of my original patch, plus three fixup commits,
    including an important regression fix by Sergio.
