Version

3.0.0-rc.5

Reproduction link

https://github.com/PanJiaChen/chunk-test

Steps to reproduce

1. npm install
2. add a new router (Don't add at the end)
3. npm run build
4. diff generated files

What is expected?

I only added one file, so the final result should not change other pages.xxx.js.

What is actually happening?

About.vue js file id has been changed. Caused the file moduleId behind it to change.

Every time I add a new page, it may cause the cache of other pages to become invalid.
