Dear webcompat team,
clipbaord.read & readText() have been enabled in nightly and early beta. However, this issue is still there. Can you help us investigate this a bit further and potentially will have to reach out to gsuite team to change their code accordingly? Thank you.

I did some diagnosis in https://bugzilla.mozilla.org/show_bug.cgi?id=1640222#c20. To summarize, Google Docs is using document.execCommand('paste') + content_capabilities property in a built-in extension allowing execCommand to run and paste from webcontent.
