Hi @kohlikohl, thank you for you contribution 🙂
I just saw #3542 which was opened earlier that seems to address a similar problem, but goes a bit further in fixing it. Would you mind heading over to that PR to see if that fixes your issue? 🙂

[kohlikohl]

@pichlermarc - ahh, #3542 looks great and works for me too. I'll close my PR and issue.
Liebe Grüsse nach Wien! :)
