Hey @quaquel can you please review the changes for this pull request.

This is a part of the code base that I am not intimately familiar with, so I need some more time. I hope to get to it somewhere in the coming days.

Thanks for this PR, this is indeed an useful edge-case to catch.

Having your first PR go through without any review comments is something that doesn't happen that often, great work.

Thanks @EwoutH, I just happened to be familiar with code.
