(From update of attachment 47844)
This is not quite right.  Both fixed and absolute positioned objects can be
added to RenderView. so you can't just use the list as is like that.  I wasn't
suggesting that you change how you detected and added the objects.  The way you
did that in your old patch is still necessary.  The count just lets you not
keep a whole separate list, since you can walk the RenderView's list and check
if the object is fixed positioned (and if so use it).

Rename the variable in ScrollView to m_fixedObjectCount rather than
m_positionedObjectCount.
