BUG: Accessibility errors

GrapesJS version

• I confirm to use the latest version of GrapesJS

What browser are you using?

Chrome 141.0.7390.123

Reproducible demo link

https://grapesjs.com/demo.html

Describe the bug

Our application serves clients that require all pages to be accessible for all users. I am running the latest grapesjs libraries:

    "grapesjs": "0.22.13",
    "grapesjs-blocks-basic": "1.0.2",
    "grapesjs-preset-webpage": "1.0.3",

How to reproduce the bug?

1. Install WAVE Evaluation Tool browser plugin.
2. Load the demo page: https://grapesjs.com/demo.html
3. Run the WAVE tool. If you add the browser extension's button to the toolbar, just hit the button: <img width="24" height="24" alt="Image" src="https://github.com/user-attachments/assets/68efb24d-d5f2-4e14-82c0-476ca0cf6c94" />

What is the expected behavior? For my application (that employs your library), we must fix all Errors and Contrast Errors reported by WAVE. I would expect 0 errors, 0 contrast errors. Non-zero Alerts and all other reported categories are acceptable.

What is the current behavior? Running WAVE on the grapesjs demo page, it currently reports 80 errors and 3 contrast errors.

If is necessary to execute some code in order to reproduce the bug, paste it here below:
