35644 - turning off sidebar decouples scrollbar

Status: VERIFIED DUPLICATE of bug 24696

(SeaMonkey :: Sidebar, defect, P3)

Description

[lidl]

Start a mozilla with the sidebar enabled, and visit a webpage
that causes a (vertical) scrollbar to appear.

Turn off the sidebar via the pulldown menu.

The screen will redraw, without the sidebar.  This is good.
 
Then try scrolling the window by grabbing the scrollbar on the right
with the mouse pointer.  Notice that the scrollbar moves, but the
on-screen content doesn't move.

If you exit the browser, and then restart it on the same page, it
will start without the sidebar, and this time the scrollbar will
operate as it should.

(For what it's worth, I have seen this on both BSD/OS 4.0.1 and 4.1,
using the GTK libraries as the windowing system.  It probably affects
more than just this platform, but I don't have any way to test that.)

I see this also, sending to trudelle. Occurs on 4/12 M16 builds on linux only, 
okay on win98. Marking pp and changing platform to linux so it won't be 
intrepreted as bsd specific.

Could this be related to bug 26658, "linux: Scrollbars in browser sometimes go 
free, stop working", M18?

Confirming bug report per comments by [e-mail].

Either bug #26658 or bug #24696 (but the core bug is bug #34033 per pav)
Marking dup of 24696.
