[Bug] Clipboard Write Failed in Pyre xNFT

[birdmanmandbir]

The error in browser console is:

Uncaught (in promise) DOMException: Failed to execute 'writeText' on 'Clipboard': The Clipboard API has been blocked because of a permissions policy applied to the current document. See https://goo.gl/EuHzyv for more details.

This is not an issue with Pyre; I opened Pyre using the xNFT, but the outer iframe did not have the allow="clipboard-read; clipboard-write" attribute set, so the Pyre copy function cannot be used within the xNFT iframe.
