Description

Bug report

Enable lazyCompilation, and because of the micro frontend, I need to set output.library.type to umd. At this time, an error will appear during the first load. After refreshing the page again, it will become normal.

What is the current behavior?

If the current behavior is a bug, please provide the steps to reproduce.

What is the expected behavior?

no mistakes
