Hey, I'm working on porting my company's Chrome/FF extension to Safari using the xcode converter tool.

The way our popover currently works is we're using a very minimal amount of JS to show a loading state while we inject an iframe that includes the actual content.
This works just fine on other browsers but for some reason on Safari the iframe's content is empty (the body and head are empty) and I don't see a request going out for the iframe's src url in the network tab. I should note that the iframe src url is correct and points to a valid HTTPS url so there should be any mixed content or security related issues.

Are iframes not allowed in the popover in Safari for some reason?

Thanks!

This should be supported. Can you send an example extension project as part of feedback via Feedback Assistant so we can look at it?

I submitted an example extension that should allow you to reproduce the issue, I hope this can be resolved quickly so we can launch our extension on Safari, our users already started asking for it!

Great to hear! Thank you for looking into this so quickly.
Is there a time frame for the fix to hit stable? Is it going to be done via Safari update or Xcode update?

This would be fixed in a future Safari update.

Facing similar issue when loading an IFrame in popover. Is this fixed? Does it need more permissions or preference changes if IFrame source is cross-domain? The IFrame does not even load safari-web-extension://{extension-id}/some_resource.html for me

Not sure when this will be properly fixed on Safari but it's fixed on Safari Technology Preview (Release 115 (Safari 14.1, WebKit 15611.1.3.5)) for me so it'll probably get to Safari sometime soon-ish in the future, I'm not sure what their deployment cycle looks like.
For now, just to unblock deploying my extension, I implemented a workaround for Safari which opens my site's homepage instead of the popup.

I hope this helps!

For me, iframe is loading inside the popover. But it's loading extremely slow. The popover loads almost ten seconds after i click on the toolbar item.
