Describe the Bug

bug_sourcemap.zip

astro.config.ts

import { defineConfig } from "astro/config";

export default defineConfig({
  compressHTML: false,
  build: {
    format: "file",
    // inlineStylesheets: 'never',
  },
  vite: {
    build: {
      assetsInlineLimit: 0,
      minify: false,
      sourcemap: "inline",
      rollupOptions: {
        output: {
          compact: false,
          // sourcemap: 'inline',
        },
      },
    },
  },
});

/dist/_astro/index.astro_astro_type_script_index_0_lang.CQbe2ZHP.js with sourcemap: false and minify: true.

What's the expected result?

I need a code with sourcemap: true and minify: false for debugging.
