42315 - Scrollbar doesn't redraw correctly when page length changes

Status: VERIFIED DUPLICATE of bug 34218

(Core :: XUL, defect, P3)

Description

[Peter Stuge]

When eg. an IMG without the height parameter has loaded and is shown, it usually
causes the page length to change.  When this happens the scrollbar (moving part
of what I call the scrollbar-area) gets resized, usually the new scrollbar is
smaller than the old.  The old scrollbar is however not removed from the
scrollbar-area before the new is drawn, on top of the old.  The old scrollbar
disappears when the new scrollbar is moved over the part of the scrollbar-area
that was covered by the old and everything WORKS, but it's caused me (the user
:) to mistakenly try to drag "unused" parts of the scrollbar-area.
I suppose the solution is to clear the entire scrollbar-area before drawing the
new scrollbar, or clearing the new "unused" part of the scrollbar-area after
having drawn the new scrollbar.

I've seen this, and I know it's a dupe, but I cannot find the dupe. I'll verify 
it and hope the owner knows where the dupe is.

Changing OS to all, confirming and changing component to XP Toolkit/Widgets.
