Thank you for the pull-request. I've merged it into the release branch (a temporary branch). Eventually it will be merged into the 1.5.12 release.

Sorry for the late reply (we had some private affairs here).

I now have a development VM to test such previews here. The MarkusTestv1.5.12-Preview.zip works for me as intended.
