Whenever I get a new email, a red dot appears in the Chrome tab like this:

I tried disabling the notification via Settings->Privacy->Content Settings->Notifications->Manage Exceptions... but to no avail (I still see the red dot):

The notifications are really distracting! it's hard not to feel compelled to check my email when I get the notification.

How can I disable Gmail tab dot notifications?


Chrome Version       : 56.0.2924.87

What steps will reproduce the problem?
1. Navigate to gmail.google.com
2. Login to your gmail account 
3. Observe a dot appears in the Chrome tab when a new email message arrives
4. Try to disable notifications via Settings->Privacy->Content Settings->Notifications->Manage Exceptions... (see screenshot above).
5. Observe that you are unable to disable the mail.google.com notification. It appears to be locked as Allow by a network adminstrator.
6. Try to add a custom Block rule for "mail.google.com"
7. Observe that the dot still appears when you get a new email message. It appears to not be possible to disable this.

What is the expected result?

I should be able to disable the new mail notification (dot in the tab).

What happens instead of that?

I'm unable to disable it resulting in distraction, lost productivity, and costing Google $$$.

Please provide any additional information below. Attach a screenshot if
possible.
