683750 - "Clearing a single item from the Location bar history" doesn't work properly in Firefox 7 betas

Status: RESOLVED DUPLICATE of bug 636992

(Firefox :: Address Bar, defect)

Description

[Sam]

User Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.21) Gecko/20110830 Firefox/3.6.21
Build ID: 20110830092825

Steps to reproduce:

1. Open any webpage in tab, leave it open.
2. Find it's entry in AwesomeBar (I did it by URL)
3. Hit "Shift+Delete"


Actual results:

4. this entry disappears from the current list in AwesomeBar
5. but type it again and it's there 

PARTIAL REGRESSION:
it only happens when page in question stays open in A tab. If I close it, "Shift+Delete" works just fine.


Expected results:

As per http://support.mozilla.com/en-US/kb/Clearing Location bar history/
it should delete webpage entry from history when I focus it and press "Shift+Delete" regardless if that webpage is open in the browser.
