Accessibility Issue: Dynamic type fontsizes are unsupported

Description

We are trying to fix all accessibility issues on our app, and noticed this warning with textinput with iOS Accessibility Inspector while running on audit

allowFontScaling={true} has no effect on this warning

<View style={{flex: 1, backgroundColor: '#fff'}}> <TextInput style={{padding: 20}} placeholder="Type here..." allowFontScaling={true}></TextInput> </View> </View>

How can we remove this warning?

Steps to reproduce

1. Run the below sample application on iOS simulator or a real device
2. Select 'Accessibility inspector' from Xcode developer tools
3. Run an audit on the screen
4. Will get the below error for text input
   " Dynamic Text font sizes are unsupported. User will not be able to change the font size of this element"

Is there anything missing here?

Inizia con il reproducer obbligatorio ed esegui il suo esempio TextInput tramite l’audit di iOS Accessibility Inspector descritto nell’issue. Traccia il modo in cui React Native 0.79.2 gestisce allowFontScaling per iOS TextInput, quindi verifica che l’avviso segnalato „Dynamic Text font sizes“ sia risolto senza introdurre regressioni nel comportamento dell’esempio.
