Accessibility [aria-hidden] issue after closing a Fancybox with thumbnails

[phucbm]

Describe the bug

I got this error in the console log after open then close a image gallery with thumbnails

Warning

Blocked aria-hidden on an element because its descendant retained focus. The focus must not be hidden from assistive technology users. Avoid using aria-hidden on a focused element or its ancestor. Consider using the inert attribute instead, which will also prevent focus. For more details, see the aria-hidden section of the WAI-ARIA specification at https://w3c.github.io/aria/#aria-hidden.
Element with focus: div
Ancestor with aria-hidden:

I noticed the error only show when I select or move the the slides that were not visible from the beginning. For example, this demo has 3 images visible on page load and the rest are hidden.

Viewing the hidden images will throw the accessibility error.

Reproduction

This issue can be seen right on the docs page here https://fancyapps.com/fancybox/plugins/thumbs/

Hi,

The upcoming next major release will use the <dialog> element and this problem will be avoided. And you can safely ignore that warning.
