Are you sure the code you provided can reproduce the problem? I still can’t reproduce it using the demo you provided. I get the same result in dev/prod mode.

I cloned from my git repository, yarn and yarn build ,eveything was normal. Then I deleted node_modules in my local file, yarn and yarn build,got the same result. I should have checked more,sorry for opened this issue.
