Bug summary

With a layout like this, when I navigate to a regular stack screen from a bottom sheet, it opens the stack within the bottom sheet as opposed to a stack push

<BottomSheet
  screenOptions={{
    backdropComponent: renderBackdrop,
    enableDynamicSizing: false,
  }}
>
  <BottomSheet.Screen name="(main-stack)" />
  <BottomSheet.Screen name="sheet-1" />
  <BottomSheet.Screen name="sheet-2" />
</BottomSheet>

// main stack
<Stack>
  <Stack.Screen name="regular-stack" />
  <Stack.Screen name="modal-screen" options={{ presentation: "modal" }} />
</Stack>

// sheet-1
<View>
  <Button onPress={()=>router.push("/regular-stack")} />
</Stack>
