I upgraded the rspack from v0.4.3 to v0.4.4 on the Vant website, then I noticed that some CSS were missing:

• v0.4.3:

• v0.4.4

Reproduce Steps

1. git clone git@github.com:youzan/vant.git --branch rspack_repro_1223
2. pnpm i
3. pnpm dev
4. open http://localhost:8080/mobile#/en-US/button
5. Inspect the demo-button-row element:

You can override @rspack/core in the root package.json to v0.4.3 to compare the build results.

I have tried to provide a minimal reproduction, but it is hard to reproduce this issue in the demo project.

I've noticed that this issue can't be reproduced in the latest commit:

@bvanjoi because I have manually reverted the Rspack version...

What I meant was the latest commit of rspack: 0b9a919a2001877acd0cd54ac28b8f6eb72b37d9

@bvanjoi haha, good news 👍

Closing this as @rspack/core@0.4.5 functions as expected
