Description Carlos J. 2022-10-17 05:00:33 PDT

Try to send a message from an iframe running a contentscript to the extension page containing the iFrame. 

Sample extension:
https://github.com/carlosjeurissen/webext-tech-demo-extensions/tree/main/issues/safari-9637664-messaging-api-from-content-script-frame

If it works (like in Google Chrome), the text of the extension page should change to "success".

Just tested in Safari Technology Preview 192, and the issue persists.
