Turn around for previewMainTemplate Option Ignored, Default Template Used Instead

[Shadowrunner11]

The bug is described in #28300

IMPORTANT: I am already working in the solution since it is needed to implement a custom preset for OAuth purposes I am working in too. this turn around temporary since I do not have much time these days, any help is very much appreciated.

What I have done as temporary turn around is to proxy the implementation of path.join like this

// scripts/hooks.js
const path = require('path');
const originalJoin = path.join;


path.join = new Proxy(originalJoin, {
  apply: function(target, thisArg, argumentsList) {
    if (argumentsList[1] === "templates" && argumentsList[2] === "template.ejs") {
      // change to point to your custom ejs you want to use
      return join(__dirname, "..", "customTemplate.ejs");
    }

    return Reflect.apply(target, thisArg, argumentsList);
  }
});

And then created a cjs file that invoques storybook cli in other to be used directly with node and not read from node_modules since in my CD workflow using pnpm something breaks

// customStorybook.cjs
require('storybook/index');

So I change my package.json scripts that are using storybook cli accordingly, notice that I require the hooks file before

{
    "storybook": "node -r ./scripts/hooks.cjs ./customStorybook.cjs dev -p 6006 --no-open",
    "build-storybook": "node -r ./scripts/hooks.cjs ./customStorybook.cjs build"
}

If I run the 'pnpm build-storybook' script the final static-storybook/index.html now is taking my custom tempalte instead of the default provided by the manager builder of storybook
