Extend MapExample to use dynamic snap points for both modals

[willcray]

How would one extend the MapExample to use dynamic snap points that update to fit the content of the modal that is currently being presented?

Using the dynamic snap points guide doesn't result in fluid, dynamic height changes according the content of whichever modal is being presented.

Dynamic snap points work when the PoiListSheet is presented. If you click into one of the locations, the height adjusts appropriately to the content of the PoiDetailsSheet modal. But if you click the close button to return to the PoiListSheet modal, the height stays fixed at the value of the PoiDetailsSheet.

How can you make it so they dynamically adjust to whatever is on the screen as you present and dismiss two different modals?
