Steps to reproduce the problem:
1. Open my accounts
2. changing account to google+ account which is connected with youtube channel
3. open new tab and it changes back to default account

What is the expected behavior?
I need to change to an account which I use on youtube, so I could go to google support and it would see my youtube channels account and I would be able to get verified icon for 100 000 subscribers

What went wrong?
Each time when I go to support page or any other page. It changes back to my default gmail account which doesn't have 100 000 subs and support site can't see my youtube 100 000 subs to get me verified

Did this work before? No

It is really annoying, I'm surprised why I can't change accounts by default with easy steps. It seems obvious to have that feature
