Embed doesn't work when within popup preview on Circle site

[rawveg]

An interesting little feature - when I see the preview of this post in the main list of threads, the output works perfectly. When I click on the post and it opens in the popup (still within the Circle site) I see this:-

But then bizarrely if I click on the expansion icon in the toolbar to open up the post full screen it works again. I wonder if it’s circle pulls in the post as remote content when it’s being opened in the popup?

Thanks @rawveg interesting that Circle would possibly pull remotely for a popup causing the super strict outside access restriction to kick in. Will take a look - thanks 🙏
