Auto-Sign-in broken on Release and Nigthly channels

Auto Sign-in of passwords is broken on Release and Nightly channels with Settings>Passwords>Auto Sign-in = Enabled.

Expected result: Sign-in with one click
Actual result: Sign-in as if Auto Sign-in disabled.

I’ve noticed the same issue with a regular release. Saved signon’s most often do not work. Disqus for example. Twitch, Facebook, youtube,… none of those are working with it enabled.
