Clean up the state of the NestedScrollView inside the CoordinatorLayout. Use to test if this would work before subclassing CoordinatorLayout and calling the protected method directly.

BottomSheet.java

try {
            Class c = parent.getClass().getSuperclass();
            Method cleanupLayoutState = c.getDeclaredMethod("cleanupLayoutState", View.class);

            if(!cleanupLayoutState.isAccessible()) {
                cleanupLayoutState.setAccessible(true);
            }

            cleanupLayoutState.invoke(parent, this);

            Log.i("BottomSheet", "invoked method");
        } catch (Exception ignored) {
            Log.e("BottomSheet", ignored.getMessage());
        }
