// TODO: The following line should have been:
//
//   const unlockedApis = unlock( blockEditorPrivateApis );
//
// But there are hidden circular dependencies in RNMobile code, specifically in
// certain native components in the `components` package that depend on
// `block-editor`. What follows is a workaround that defers the `unlock` call
// to prevent native code from failing.
//
// Fix once https://github.com/WordPress/gutenberg/issues/52692 is closed.
