BUG: canvas.script entries do not respect an "import map"

https://github.com/GrapesJS/grapesjs/issues/5353#issuecomment-1704023749

have you tested them?

when trying

      canvas: {
        scripts:[                                    // scripts for the "iframe"
          { src:'/js/ImportMap.json',               type:'importmap' },
          { src:'/js/common-applet-support.esm.js', type:'module' },
        ],
        styles: [                                // stylesheets for the "iframe"
          '/css/common-applet-support.css',
        ],
      },

in the current version of GrapesJS, I get the following (expanded) error message in the browser log:
