302940 - First element in tree is selected when expanding a folder

Status: RESOLVED FIXED

(Core :: XUL, defect)

Description

[Pardal Freudenthal (:ShareBird)]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050731 Firefox/1.0+
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050731 Firefox/1.0+

When you open the bookmarks sidebar, initially there is no element with focus.
If you click on any "+" beside a folder (except the first one) on the sidebar,
the very first element will get focus. 
This can be very annoying if you have a large list of bookamrks folders. If you
scroll your list on sidebar (using the mouse scrollrad) to point to a folder on
the bottom and click on "+" the list will jump to the very first element on the
list.
A similar problem occours also with the History sidebar.
The issue started with build 20050726. 

Reproducible: Always

Steps to Reproduce:
1.Create a new profile. 
2.Open the bookmarks sidebar.
3.Click on the "+" signal beside the third folder on it ("Firefox and Mozilla
Links").

Actual Results:  
Notice that the first folder ("Bookmarks Toolbar Folder") get focus. 

Expected Results:  
The old behaviour was if you click on the "+" beside a folder, the focus stills
on the last selected element. If no element was selected (as you open the
sidebar at the first time), it should still with no element selected.

I think this needs to go under XP Toolkit/Widgets: Tree. Someone correct me if
I'm wrong.

This is probably fallout from bug 280153.

This was fixed by the recent check-in for bug 280153.
