Feature Request: Enhance scroll negotiation to pass off gesture to nested scroll view at max detent

[lxr-mwhite]

When the bottom sheet reaches its maximum detent, would it be possible for a continuous upward scroll gesture to be handed off to nested scrollable content? Currently, the BottomSheet appears to continue handling the upward gesture after it is fully expanded (onPositionChange fires with the same value multiple times).

I can provide a screen capture if necessary but I'm just looking at how Apple handles this in some of its own apps.
The sheet will transfer the gesture to the nested scroll view and allow it to start scrolling in a single pan gesture, as opposed to one gesture that moves the sheet to its top position, then another gesture to start scrolling the nested content.

Let me know if a screen capture would help, but the basis of this request mostly comes from using the sheet component in Apple's native apps.

Thank you for taking the initiative for providing a native bottom sheet for React Native apps!

Hello! Thanks for the suggestion and the kind words. Apple’s implementation appears asymmetric. An upward drag can be transferred from the sheet to the content, as you’ve noted; however, a downward drag that scrolls the content is never returned to the sheet, as seen in the recording below. Could you clarify what behavior you’d expect for downward drags?

While it seems inconsistent I think that behavior might be intentional so that you don’t accidentally close the sheet. I was thinking it could work the same way as the recording you shared.

Thanks! We’ll look into it.
