Fancybox 3 bug in Firefox?

Question

fancyBox

Hello!
I noticed that the fancybox 3 plugin (official site: https://fancyapps.com/fancybox/3/ ) has a very annoying bug when using firefox. A pop-up window opens and starts to "lag" - some of the elements on the site come out ahead of the photos.
At the beginning, I thought there were problems with z-index on my site, but the same is true on the official site. Has anyone found the same errors and somehow corrected them?
At the same time, everything is correct in opera and in chrome.

I noticed the same problem, IMHO will be corrected in the next releases. And while there is what is.
