* fix: Workaround Android 12 webview crash

A crash occurred due to combining webviews with Android 12's new scroll
overflow behavior. Applying `opacity: 0.99` prevents the crash from
occurring. This change should be viewed as a temporary fix while we
await a more appropriate solution for the `react-native-webview`
library.
