I would like to add compilerOptions.isCustomElement vue option and, to do so, I have added the following configuration to the extension.config.js file:

module.exports = {
  config: (config) => {
    config.module.rules.push({
      test: /\.vue$/,
      loader: require.resolve("vue-loader"),
      options: {
        compilerOptions: {
          isCustomElement: (tag) => tag.startsWith("ion-"),
        },
      },
    });

    return config;
  },
};

However, it looks like extension.js it is already adding its own rule for vue files after this one, which is causing the following error:

× ModuleError: At least one <template> or <script> is required in a single file component.

Is there any other way to do what I need?
