[tim-prom]

GrapesJS version

• I confirm to use the latest version of GrapesJS

What browser are you using?

Chrome v131

Describe the bug

How to reproduce the bug?

1. Add an img to the canvas with an invalid URL in the srcset
2. Check the network tab in Chrome dev console - the asset request correctly returns a 404, but the browser continues to make this request in an infinite loop.

What is the expected behavior?
img is not requested again after the first 404, and ideally shows same fallback as when there is a broken src

<div id="gjs">
  <img srcset='https://dsfdsfsdfdfsdf.com/brokeimg.png'/>
</div>

const editor = grapesjs.init({
  container: '#gjs',
  fromElement: 1,
  height: '100%',
  storageManager: { type: 0 },
});
