Issue: Keyboard on iOS 18 changes from uppercase to lowercase when changing the text input field
Labels: Platform: iOS,Issue: Author Provided Repro,API: Keyboard,Needs: Repro,Needs: Attention

### Description

I encountered an issue where the keyboard changes from uppercase to lowercase when switching focus between two TextInput fields. Specifically, when focusing from Text Input Field A to Text Input Field B, and then back from Text Input Field B to Text Input Field A, the keyboard behavior unexpectedly switches between uppercase and lowercase.

This issue occurs on iOS 18.

### Steps to reproduce

1. Add two TextInput fields.
2. Focus on TextInput 1 and input some text (e.g., "T").
3. Focus on TextInput 2 and input some text (e.g., "B").
4. Focus back on TextInput 1.
5. Focus back on TextInput 2.
6. Observe that the keyboard switches from uppercase to lowercase and the first letter of the text remains uppercase.
