I confirm that this bug 903011 still exists in 239-5.

Two other bugs reported at the upstream

https://github.com/systemd/systemd/issues/9502
https://github.com/systemd/systemd/issues/9578

probably have the same cause because the same workaround

https://github.com/systemd/systemd/issues/9512#issuecomment-404270548

prevents all of them.
