What steps will reproduce the problem?
1. Try to log in with my username.
2. Does not autocomplete the password.
3. Go look for the password in my chrome settings.
4. Password does not appear in chrome settings.
5. Go look for the password in passwords.google.com
6. Password appears there.

What is the expected result?

My password should autocomplete.

What happens instead?

My password does not autocomplete.

Please provide any additional information below.

This is the most frustrating  functionallity I ever had. It happened in tens of pages that I decided to use chrome password manager to create a password and then, a couple of weeks later I try to login and the password is just not there, and nowhere to be found in chrome settings. I just learned about passwords.google.com, but I had to recover multiple passwords because of this bug.

It happened both with my personal account as well as with my work account.

Attach a screenshot or the output from chrome://password-manager-internals if possible
