UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36

Steps to reproduce the problem:
1. Sign into gmail or youtube with a different user.

What is the expected behavior?
Chrome should sync my normal user.

What went wrong?
Chrome will switch to sync a different user.

Did this work before? Yes 

Chrome version: 69.0.3497.100  Channel: n/a
OS Version: 
Flash Version: 

I was asked to open a new bug report:

https://bugs.chromium.org/p/chromium/issues/detail?id=896952

So I'm opening this one. When I sign out of google sites to sign in using a different user, Chrome 70 will stop syncing and switch the different user.

In Chrome 69 (which I have downgraded to now), does not have this problem.
