This is for 2.0.*? I was about to discovering it with FsCheck but ordinary job distracted me thank you, @davhdavh.

For the moment I can't proceed, please read this temp announcement #250.

Have nice day! :)

Latest on nuget, so 2.0.257+.
Np on delay for fixing, a few weeks wont make any difference for me.

I think I fixed your issue (see tests in referenced commit), but I'll let you confirm before officially closing this issue. Thanks for reporting it!
