  @rsbuild/plugin-svelte: 1.0.1-beta.11 => 1.0.1-beta.11

Details

When running Docker Desktop (with the WSL2 engine) on Windows 11, the dev server doesn't recompile files when HMR is triggered by saving changes, even though the websocket is connected and the page reloads.

The testing project where this occurs was created using npx create rsbuild@latest with the Svelte template.

In rsbuild.config.mjs, I am using usePolling: true in dev.watchFiles.options, similarly to my previous Vite setup, since without it, WSL doesn't register changes made from a Windows application.

Reproduce Steps

1. Execute docker compose up -d in the folder of the example project.
2. Open http://localhost:3000 in a browser.
3. Modify src/App.svelte and save the changes.
4. The page in the browser gets refreshed but the changed files don't get recompiled.

If the dev server doesn't recompile files after saving changes, it should be related to Rspack's watcher (watchpack)

Have you seen any logs like this: webpack/watchpack#187?
