Reproduce Steps

// rsbuild.config.ts
import { Rspack, defineConfig } from '@rsbuild/core';
import { pluginReact } from '@rsbuild/plugin-react';

export default defineConfig({
  plugins: [pluginReact()],
  dev: {
    writeToDisk: true, // inspect output
  },
  tools: {
    bundlerChain(chain) {
      chain.plugin('TestPlugin').use(TestPlugin);
    },
  },
});

class TestPlugin {
  apply(compiler: Rspack.Compiler) {
    compiler.hooks.thisCompilation.tap('TestPlugin', (compilation) => {
      compilation.hooks.runtimeModule.tap('TestPlugin', (module) => {
        if (module.name !== 'css_loading' || !module.source) return;
        const originCode = module.source.source.toString('utf-8');

        module.source.source = Buffer.from(
          originCode
            .replace(/document\.(getElementsByTagName|querySelectorAll)/g, `(globalThis.APP_ROOT||document).$1`)
            .replace(/document\.head/g, `(globalThis.APP_STYLE_ROOT||document.head)`),
          'utf-8',
        );
      });
    });
  }
