Problem with transparent headers

[arminbashizade]

If header layout is transparent, the header row can be seen behind the pinned header moving up or down.

In this implementation a PinnedSection view overlaps real list item. If PinnedSection becomes transparent, then you will see real item. It might be possible to make real list item invisible, but this requires special implementation I have no time to write. Thus currently it is not supported.
