Bug report

Describe the bug
A clear and concise description of what the bug is. If applicable, please add screenshots/videos.

Steps to reproduce

Steps to reproduce the behavior:

1. Open a bottom sheet page that contains a texfield
2. autofocus or focus on the textfield
3. slide down the bottom sheet to close but lift your finger only when above the open keyboard

Expected behavior

The bottom sheet should close. At the moment the sheet collapsed but stays opened (the keyboard is still visible).
onModalDismissedWithDrag is not called.

Additional context

My guess is that onModalDismissedWithDrag is only called when lifting the finger, but it's not registered when above the opened keyboard.
