Automatich assignement does not work, if some has in the title category/portname@flavor. Not many people use till now, but I think there will more in the future. Flavors are relative new, but we will have more in the near future. So I think some more people which mean this is more correct this in the title and it is not really good if the assignement is not working, more cases.
Fix was committed to git repo [1] and deployed to main instance [1] https://github.com/gonzoua/bugzilla/commit/217727fe0d504fde98cdd71577a06e6bcf850ae8
