Confirmed, this looks to be fixed 🙏

Closing for now, if we detect other issues after upgrading I'll re-open/open a new issue.

On further testing this only appears to have been fixed when a copy results in the clipboard only containing text nodes. If a whole paragraph node is copied then a paste into a quote still clears the quote which feels unexpected.

I've worked around that in our editor here https://github.com/TryGhost/Koenig/pull/1297/files but I'm re-opening the issue as it still feels like a core concern. However, please feel free to close if this expected behaviour crosses the core/userspace concern boundary.
