[iOS 26]: Messages “To:” field hidden when sharing via Share

[DejaVuRox]

Description

On iOS 26+, using React Native’s built-in Share or react-native-share to share a URL sometimes opens Messages as an embedded sheet and the “To:” field is pushed off-screen. This appears inconsistent and seems related to how UIActivityViewController calculates layout for adaptive sheets.

Steps to reproduce

1. Open a React Native app.

2. Trigger a share using either:

import { Share } from 'react-native';

await Share.share({ url: 'https://example.com' });

import Share from 'react-native-share';

await Share.open({ url: 'https://example.com' });

3. Select Messages from the share sheet.

4. Observe that the “To:” field may be pushed off-screen, sometimes working correctly and sometimes not.

Expected Behavior:
The Messages sheet should always display the “To:” field correctly.
