Summary: A layout-impacting style change will trigger a layout effect hook within `TextInput`. This hook fires a ViewManager command to set the text input based on the known JS value: https://github.com/facebook/react-native/blob/d82cd3cbce1597512bb2868fde49b5b3850892a0/Libraries/Components/TextInput/TextInput.js#L1009 The JS value is determined using `value` if set, falling back to `defaultValue`. If a component uses `TextInput` as an uncontrolled component, and does not set this value, the command wipes text input back to the default value. This does not happen on re-render of the JS side, despite setting text prop, since the underlying native property never changes/triggers a rerender. This change alters the logic to prefer `lastNativeText` instead of `defaultValue` when available, to retain the updated `TextInput` content on relayout.
