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

Research direction
Start with the linked reproducer and reproduce the TextInput inside a Modal on Android and iOS using React Native 0.76.0. Trace the onContentSizeChange event from the Modal/TextInput entry points; done means the callback fires once inside the Modal, matching behavior outside it, with regression coverage for both affected platforms.
