I am a big fan of middle-clicking links to open them in the background, and then reading them later (e.g. from reddit.com).  For this, i set BrowserTab.LoadDivertedInBackground to true.  However, when a site thus loaded tries to set a cookie (I have cookies set to manually accept or reject), that tab immediately jumps to the foreground.

Reproducible: Always

Steps to Reproduce:
1. Set "Keep Until" to "ask me every time" in the Privacy Prefs for cookies.
2. Set BrowserTab.LoadDivertedInBackground to true in about:config
3. middle-click a link to a page that tries to set a new cookie.
Actual Results:  
New tab will jump to the foreground in order to ask about the cookie.

Expected Results:  
Either:
The cookie dialog should be backgrounded with the tab.
Or:
The cookie dialog should come up without foregrounding the tab.
