CollapsingToolbarScaffold consumes horizontal flings

[sunian]

When a CollapsingToolbarScaffold is wrapping a horizontally scrolling component, then horizontal flings on it do not work. For example, consider a vertical feed with horizontal shelves :

CollapsingToolbarScaffold {
   LazyColumn {
      LazyRow
      LazyRow
      LazyRow
   }
}

In this set up, vertical flings on the LazyColumn works just fine, but horizontal flings on any of the LazyRows do not work. I believe this is caused by the ScrollStrategy implementations always consuming the full horizontal velocity of flings, when they should consume none of the horizontal velocity.
