Fix modified nuxeo-home page never ends loading (on Firefox only)

When modifying the nuxeo-home page, on Firefox only, the page looks like never fully loaded.

Steps to reproduce:
In Studio

• take a standard new project
• modify in "Designer > Resources" the "nuxeo-home.html" page in commenting the 2 nuxeo-cards section Tasks and Favorites => There remains only 2 active nuxeo-cards in this page

Take a new 9.10 instance, (hotfix it) and start it => Open http://localhost:8080/nuxeo/ui/#!/home in Firefox, Chrome and Edge => Everything fine (default nuxeo-home page)

Deploy your project and open http://localhost:8080/nuxeo/ui/#!/home again in Firefox, Chrome and Edge => new nuxeo-home page is there => Everything fine in Chrome and Edge, but on Firefox, the page keeps loading
