CleanId function not working with MJML code

Question

This issue is about MJML code but I think this is more about grapesjs than grapesjs-mjml

There is a function that remove unnecessary IDs in src/code_manager/model/HtmlGenerator.js. This function is working well on HTML tags, but not on MJML tags.

What I found is

      htmlOpts.attributes = (mod, attrs) => {
        const { id } = attrs;
        console.log(attrs) // this log will return all dom elements in HTML, not in MJML
        if ( id && id[0] === 'i' && !mod.get('script') && idRules.indexOf(id) < 0 ) {
          delete attrs.id;
        }
        return attrs;
      };
