切换两个子应用出现错误error occurs when execute script in sandbox: Error: only one instance of babel-polyfill is allowed

**If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.

What is the expected behavior?

需要怎么避免

这个错误是 babel-polyfill 抛出的，需要确保 babel-polyfill 的代码只执行一次，即可以将 babel-polyfill 仅在主应用中执行

确实两个子应用都执行 babel-polyfill ，但这个被包含在第三组件无法修改，通过更换组件解决了
