I have this domain: https://codesandbox.io/. Shouldn’t be enough? I have found this code at Discourse where it whitelists just some iframe attributes:
If I include the attributes height and weight the iframe works fine, but I would like to allow the other attributes too.
Is there a way of allowing all codesandbox iframes? I thought including just the domain it would work.
Thank you!
EDIT:
I have tried adding this url in whitelist but it is not working neither.
