33707 - Closing first window after opening second breaks scrollbar

Status: VERIFIED DUPLICATE of bug 24696

(Core :: XUL, defect, P3)

Description

[Devin Carraway]

Applies to build 2000032808 and nightly builds back to around M14.  Start
mozilla the usual way; window opens, mozilla.org loads.  Open new window either
from File menu or Button2 on a link.  New window opens, all seems well.
However, if after the second window opens, the original one is closed, the
canvas in the second window redraws once (correctly), after which that second
window's UI becomes unresponsive to events relating to mouse position.  The
first window closes by all appearances normally.  The second window's scrollbar
can be moved, but doing so does not cause any movement in the canvas.  Less
reproducibly, the menus may respond to mouse clicks but menu entries don't
highlight when the mouse passes over one, and submenus don't pop open when mouse
hovers over them.

Terminal output as follows:

i described how this bug responds to various mouse/kb input in bug 33230 . Not
100% sure that was the right place to comment about it though.

I cannot reproduce this using the steps described above (either the scrollbar
or the menu issues noted)[using 1000032909 linux]. However, the general problem
noted, where the scrollbar no longer causes the content area to be scrolled, is
a known problem -- bug #24696 -- which people have triggered by several 
different methods. Marking this bug a duplicate of 24696, but please reopen if
I'm missing something.
