Doesn't work inside iframe #439

Lazy loading images using the library works without problems, but when i include my page in another page inside an iframe it suddenly stops working. I have a bunch of images that have the data-src attribute and I just call lazyload after adding them to the page

new Lazyload(null, {
  rootMargin: '100px',
});

I also tried setting a root element for the intersection observer but without success.

I'm not sure if this is a problem with the library or with the intersection observer. The MDN page mentions something about iframes but I've read that paragraph 3 times now and I just don't get it 😅

Couldn't reproduce your report. As per my tests it worked exactly as expected even through an iframe. Make sure you're loading the plugin on the same page (the one inside the iframe) and not on the parent page.
