Steps to reproduce the problem:
1. set up two webservers, one with a valid tls certificate, one with an invalid one. both must request basic authentication
2. visit either page. on the one with the invalid certificate 
a warning is displayed. on the one with the valid certificate click the i in the the circle next to the url. It says the connection is insecure and you should not enter a password, even though the certificate obviously is checked before (otherwise the invalid certificate warning could not be issued).

What is the expected behavior?
The browser should display a green "secure" message next to the url before prompting for the password

What went wrong?
the browser does not display a green "secure" message next to the url before prompting for the password but rather an encircled gray i and warns the user not to enter a password when clicking the i.

Did this work before? N/A
