I found this thread as I have the same problem. I basically came to the conclusion that the Juniper SSH client has no clever way around this. So I added a custom Java applet under the "Terminal Service Resource Profiles" to a client. I added into this a JavaSSH client I found (the one I used was JTA - Telnet/SSH from
http://javassh.org/space/Download ). I downloaded jta26.jar and uploaded to the Juniper SSL using the "Edit List...", and I called it JavaSSH.
I modified the HTML to:

This forces this new Java applet to open in it's own window so the tab doesn't have any losing focus effect (the only downside is you are left with the original launch window (i.e. 2 windows for the SSH session), but not a huge problem). Also the <<PORT>> param doesn't seem to work (always passed _3389 regardless of what's put in the config window) so I manually put in 22 in the HTML, but no real hassle.
