Incompatibility with docusaurus Rspack experimental options

[rbala19]

Docusaurus version: 3.6.1 (Latest Major and minor version)
Docusaurus-plugin-openapi-docs version: 4.0.1 (Latest Version)

When I enable docusaurus-plugin-typedoc-api in my themes config and turn on rspackBundle in docusaurus's new experimental config (available for versions > 3.6), I run into a webpack error during asset bundling. Either turning off rspackBundle or commenting out the open api theme plugin fixes the build. As the experimental option is a relatively new one on docusaurus (as of the last couple of months), I'm assuming there is a bit of catch up to do with peripheral docusaurus plugins. Is support of turning both options at the same time planned at some point in the future?

In docusaurus.config.js:

 future: {
    experimental_faster: {
      swcJsLoader: false 
      swcJsMinimizer: true,
      swcHtmlMinimizer: true,
      lightningCssMinimizer: true,
      rspackBundler: true, //Setting to false fixes the build
      mdxCrossCompilerCache: true,
    },
  },

In docusaurus.config.js:

  themes: [
    '@docusaurus/theme-mermaid',
    'docusaurus-theme-openapi-docs', 
  ],
};

I doubt it's a problem in this plugin
