Should a ComposeView inside bottom sheet behavior handle scr

Question

Should a ComposeView inside bottom sheet behavior handle scroll events correctly As an example from the compose documentation ```Simple nested scrolling requires no action on your part Gestures that initiate a scrolling action are propagated from children to parents automatically such that when the child can t scroll any further the gesture is handled by its parent element ``` When I scroll up in the bottom sheet the bottom sheet first resizes to fill the screen then properly scrolls to the bottom of the content which is the expected behavior However when trying to scroll back to the top of the content ie dragging down the bottom sheet starts to collapse instead of scrolling the content down first

I have a complex map view that sits outside of compose Is it possible to pull the bottom sheet view from there to the composable Can you have a bottom sheet in a composable if the entire activity view does not exist in that composable

Thinking about this a different way maybe letting the traditional view handle the scroll is a better option ``` lt FrameLayout android id= +id bottom sheet android layout width= match parent android layout height= wrap content app behavior hideable= true app behavior peekHeight= 200dp app layout behavior= com google android material bottomsheet BottomSheetBehavior gt lt androidx core widget NestedScrollView android layout width= match parent android layout height= wrap content gt lt androidx compose ui platform ComposeView android id= +id compose view android layout width= match parent android layout height= wrap content gt lt androidx compose ui platform ComposeView gt lt androidx core widget NestedScrollView gt lt FrameLayout gt ```
