Ok, thanks! 

Well, what I suggested was only a workaround as well. 

Since the issue is gone for you and nobody else commented here, let's close

If you encounter it again, you may want to test the other workaround - feel
free to reopen the ticket. 

WONTFIX doesn't seem to be appropriate but nothing else is either :(
