Update `app/page.module.css` and it triggers full reload instead of fast refresh like this  ### Current vs. Expected behavior It should trigger fast refresh when I edit css modules. Actually, the following cases execute fast refresh correctly. 1. When I edit a native css file (like global.css) 2. When I didn't choose `App Router` at the install. ### Verify canary release - [X] I verified that the issue exists in the latest Next.js canary release ### Provide environment information ```bash Operating System: Platform: darwin Arch: x64 Version: Darwin Kernel Version 23.0.0 Binaries: Node: 18.11.0 npm: 10.2.1 Yarn: 1.22.19 pnpm: N/A Relevant Packages: next: 13.5.6 eslint-config-next: 13.5.6 react: 18.2.0 react-dom: 18.2.0 typescript: 5.2.2 Next.js Config: output: N/A ``` ### Which area(s) are affected?
