Steps to reproduce the problem:
1. Go to a link in another application such as an email message in Apple mail and click on a the link.
2. Choose "Open link behind mail"
3. 

What is the expected behavior?
Google chrome opens the link in the background (without bringing the Chrome window to the foreground.)

What went wrong?
Chrome opens the link in the *FOREGROUND*, just the same as if you had selected plain "Open link" instead.

Did this work before? Yes 68 ?

This is very annoying and has been broken for quite a while now.  It needs attention.
