44394 - Scrolling header list loses data

Status: VERIFIED DUPLICATE of bug 43679

Discovered this while testing a patch for Brendan:

Bring up a compose window.
Type in three or four addresses, e.g. 
aaa<return>
bbb<return>
ccc<return>
enough so that the addressing area now shows a scrollbar.
Use the mouse to drag-scroll the scrollbar back up.
In a debug build, I get assertions:

nsWidget::~nsWidget() of toplevel: 19 widgets still exist.
###!!! ASSERTION: node in map twice: '(node->mContent != aNode->mContent) ||
((node->mContent == nsnull) && (node->mStyle != aNode->mStyle))', file
nsFrameManager.cpp, line 1907

(four of those) and the two addresses (aaa and bbb) which were scrolled out of
visibility are now blank.
