GF-54724: Removed fixed height on stacked controls to prevent double-scrolling.  Updated documentation to make it clear that DataList is not and cannot be supported in ListActions that may stack.  Ensure that spot is not called on initial render.  Move capture and activate logic into openChanged, such that calling setOpen(true/false) works as expected.
