描述

Failing test repro
@react-native/babel-preset 的预期行为是在它们首次被引用的作用域内推迟一部分 react-native 模块的评估：https://github.com/facebook/react-native/blob/main/packages/react-native-babel-preset/src/configs/main.js#L76
这种情况不再发生(因为 @babel/plugin-transform-modules-commonjs 将源字符串传递给 lazy 回调，而不是预期的 import specifier)。参见测试 2。
