Regression: Elevation shadow fix (#48874) missing in React Native 0.78.0 stable release

[polovi]

Description

It looks like the fix for elevation shadows on Android, introduced in issue #48874 and committed in f7d78f8, is not included in the React Native 0.78.0 stable release.

This results in elevation-based shadows still not rendering correctly, despite the issue being marked as fixed.

Steps to reproduce

1. Create a simple View component with an elevation style.
2. Run the app on an Android device.
3. Observe that the shadow does not appear as expected, similar to the behavior before [Android] Elevation (elevation style prop) looks weird combined with border radius (borderRadius style prop) on RN 0.77 #48874 was fixed.
