I found the Easter egg:

It reverts cleanly on top of 5.7-rc1, and this fixes the issue.

Greg, please do not apply this to the stable series. The commit message 
doesn’t even reference a issue/bug report, and doesn’t give a detailed

Dave, Alex, how to proceed? Revert? I created issue 1094 [1].


Kind regards,

Paul

And is it committed to any tree at the moment?
