Crash on latest React Native

It's uneasy to reproduce and best I have so far is noticing that this component occasionally crashes the app on Android.

````typescript

The crash:

Deps:
- "react-native": "0.81.4"
- "expo": "54.0.8"
- "react-native-paper": "5.15.5"

Device:
- Google Pixel 7

まず、Pixel 7または同等のデバイスで、React Native 0.81.4、Expo 54.0.8、react-native-paper 5.15.5を使用して、報告されたPortalとLoadingIndicatorのケースをAndroid上で再現します。PortalとLoadingIndicatorのエントリーポイントおよびAndroidのビュー更新を追跡します。完了の条件は、断続的に発生するEdgeToEdgeReactViewGroup null-childクラッシュが発生しなくなることです。
