Android Mask not working

Description

Here is my component that renders this preloader.
Figma screenshots:

It works perfectly on iOS, but the mask doesn't work on Android.

Acknowledgements

Yes

Start with the provided Loader component and reproduce it in Expo Go on the Android emulator using React Native 0.81.5 and react-native-svg 15.12.1. Compare the mask output with iOS and inspect the Android SVG mask behavior; done means the preloader renders the intended masked segments consistently on Android.
