Flatten margin styles are not properly overriding when applied from specific to general properties

Description

By flattening the styles { marginTop: 15 } and { marginVertical: 0 }, it results in a component with margin: 0, however a "ghost" hidden component retains the marginTop: 15. A complete description can be found here https://github.com/HathorNetwork/hathor-wallet-mobile/issues/532.

Steps to reproduce

Use the flatten style syntax with a flag in a component, like: style={[{ marginTop: 15 }, flag && { marginVertical: 0 }]}

Führe das verlinkte Snack- oder reproducer-react-native-Projekt mit den bedingten Margin-Styles aus, um die Abweichung zwischen den sichtbaren und ausgeblendeten Komponenten zu beobachten. Verfolge den für die Reproduktion verantwortlichen Einstiegspunkt der Style-Zusammenführung und überprüfe, dass die allgemeine Margin-Regel die spezifische Regel konsistent überschreibt, auch bei der ausgeblendeten Komponente.
