To embed this frame in your document, the response needs to enable the cross-origin embedder policy by specifying the following response header: Cross-Origin-Embedder-Policy: require-corp

Describe the bug To use atomics - I add these headers to the html responses:

Cross-Origin-Embedder-Policy: credentialless   
Cross-Origin-Opener-Policy: same-origin

However - even without enabling partytown - this already causes some errors with some third party scripts. I'm seeing these errors in the console:

These errors happen seemingly when third party scripts try to embed some html docs. Is this a known issue?

Expected behavior no errors in the console

Partytown version 0.7.0

I'm running into a similar issue with embedding iframes (e.g. code sandbox or codepen.)

My impression is that for third party iframes/scripts to work properly, those third parties would need to set CORS headers on their documents. Is that accurate?

I'm searching for solutions but may have to disable these headers for now to fix these embedded iframes.

(By the way, Partytown is awesome! Thanks for the great tool!)

is there any solution here?

Yes, atomics are very restrictive, to the point of being almost unusable. I don't think there is a good solution here...
