TextInput onContentSizeChange triggers twice inside a Modal

Description

When using a TextInput inside a Modal, the onContentSizeChange callback is triggered twice instead of once. Outside the Modal the event triggers correctly (only once).

Steps to reproduce

1. Install and launch the application
2. Observe that onContentSizeChange triggers once (as expected)
3. Click on the "Show modal" button
4. Notice that onContentSizeChange for the TextInput inside the Modal triggers twice (unexpected behavior)

リンクされた再現用コードから始め、React Native 0.76.0を使用して、AndroidとiOSでModal内のTextInputを再現します。Modal/TextInputのエントリポイントからonContentSizeChangeイベントを追跡します。完了条件は、Modal内でコールバックが1回発火し、Modal外の動作と一致すること、そして影響を受ける両プラットフォームのリグレッションカバレッジがあることです。
