[iOS] Adding outline to `TextInput` causes it to lose focus

[SimpleCreations]

Description

On iOS, if TextInput with overflow: hidden is rendered with an outline while focused, it immediately loses focus. This also means that if outline is used to indicate focus state (like on web), the TextInput becomes impossible to interact with.

Steps to reproduce

1. Run the snack
2. Switch on "Enable outline"
3. Press on the text input
4. Notice how the keyboard closes immediately, and the text input loses focus

Don’t combine overflow:'hidden' with outline on iOS. If you must keep outline on Android, gate it: Platform.OS === 'android' && { outlineWidth: 4 }.

If you truly need clipping, keep overflow:'hidden' on the wrapper, not the TextInput, and style a separate inner border for focus.

import React, { useState } from 'react';
import { SafeAreaView, View, TextInput } from 'react-native';

export default function App() {
const [focused, setFocused] = useState(false);
return (
<SafeAreaView style={{ padding: 16 }}>
<View style={{
borderWidth: 4, // acts like an outline
borderColor: focused ? 'lightgreen' : 'transparent',
borderRadius: 6, padding: 2 // keep input corners tidy
}}>
<TextInput
onFocus={() => setFocused(true)}
onBlur={() => setFocused(false)}
style={{ borderWidth: 1, borderColor: 'gray', padding: 10 }} // no overflow here
/>


);
}

@samansalari I'd say the issue here is platform inconsistency and confusing behavior, rather than needing overflow: "hidden" or not. Plus, this bug may indicate some sort of underlying issue.

After upgrading my project to new arch I've decided to try out the new outline property instead of a previously used abspos hack. However, I've run into this issue (on iOS only), and it took me a while to narrow down overflow: "hidden" as the culprit.

@SimpleCreations Thanks for raising this, I tried reproducing it locally it worked fine on old arch seems like a new arch regression
