It paints the headers. And the problem comes about because in
LISTVIEW_Paint, a test is made for the first paint, and if it is the
first paint, the item size is updated.
UINT uView = infoPtr->dwStyle & LVS_TYPEMASK;
infoPtr->bFirstPaint = FALSE;

It has nothing to do with LVM_SETITEMCOUNT that I know, or am I missing
something? This bug is not related to the other bug.
