Thanks @Gepardgame! Great addition.

@nscuro Is it possibly to backport this to 4.12.3, please?

@Gepardgame We don't usually backport enhancements since bugfix releases are only intended for fixing of defects. However, since this is just a tiny change, I think we can make an exception here. If you want, you could raise a PR into the 4.12.x branch to backport it now (cherry-picking should just work). Otherwise, I'll do it at a later point in time.
