iframe performance issue

[TIME-GATE]

Describe the bug

sometimes open the website is very by iframe， it will be normal open this website from new page tab

Reproduction

Embedding a website via iframe can be slow to open, sometimes it gets stuck, I don't know the reproduction steps yet, it's easy to reproduce try a few times, but if I open the website directly, it's never slow, even if I clear all the cache directly.

Additional context

Hi,

Try disabling auto sizing and/or preload:

Fancybox.bind("[data-fancybox]", {
  Html: {
    autoSize: false,
  },
  preload : false
});

Sorry, I don't think there's anything else that can be done that will help.
