Summary Messages send from iFrame not received by extension popup

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.

In Safari 18.1.1, calls to chrome.runtime.sendMessage from within a contentScript of an iframe in an extension popup throws the "Error: Invalid call to runtime.sendMessage(). Tab not found." Same behaviour can be found in Safari Tech Preview 209.
