Grafana v6.x.x - Logout on browser close

In Grafana 5 it was possible to log out a user on browser close by setting parameter login_remember_days to 0.
In Grafana 6 this options has been removed, in favour of login_maximum_lifetime_days and login_maximum_inactive_lifetime_days. Setting these variables to 0 results in a constant redirect to the login page, which is logic of course.
Is there any way to log out a user when the browser is closed?

Please add a comment in this issue. And have a look at my comment in there. Thanks
