[UxSite] When using the back button, images aren't rendered properly

[evertharmeling]

Steps to reproduce:

• Vist https://ux.symfony.com/live-component
• Click on one of the 'Live component demo' blocks (at the bottom of the page)
• Then click on the back button of your browser (I used Chrome Version 103.0.5060.114 (Official Build) (x86_64))
