I was trying to build a listView with header and footer. When I enabled
SnapToItem, the header was not shown anymore. It was there, but because the list
snaps to the first Item below the header, one can only flick downwards to see
the header. This is probably not the correct behavior, since a non-visible
header doesn't make much sense. When snapping is turned off, it works as
expected. Also, the behavior is correct with the footer. It snaps correctly,
regardless of SnapToItem.
