react-native: Crash: `undefined is not an object (evaluating '_this.props.updateCellsBatchingPeriod')` when using @babel/proposal-decorators

Describe the bug Once i provision Storybook into a brand new React Native app (via react native cli, not expo), add @babel/plugin-proposal-decorators to dev dependencies, and provision the plugin in babel.config.js, app builds but crashes on launch (see screenshot).

To Reproduce Steps to reproduce the behavior:

1. npx react-native init StorybookIssue && cd StorybookIssue
2. npx -p @storybook/cli sb init --type react_native
3. add export {default} from './storybook'; to App.js; comment/remove export default App;
4. yarn add -D @babel/plugin-proposal-decorators
5. cd ios && pod install && cd ..
6. open ios/StorybookIssue.xcworkspace/
7. Run app on xcode
8. see crash

Expected behavior See Storybook Demo preview (“Hello Button”). Happy to provide a repo to repro the issue, but i figured repro steps were simple enough.

Additional context There’s no issue using legacy: true option for plugin, but unfortunately the app i’m adding storybook to uses decoratorsBeforeExport: true option. The repro steps are for a brand new app (for testing). Existing app works fine with this babel plugin.
