There's no fix, as it's a sev 6 ad it's new, meaning it's an enhancement, yet, it's still considered a bug
CSCug34460 Ability to add Distribution list as a Jabber group with Users
As it's new, no way to tell you when, or if, it will be included in an upcoming release, if you want to see it, contact you AM and submit a business case so it's presented to the BU and they can take it under consideration.
EDIT: FYI, roadmap questions cannot be addressed on CSC, such need to go thru your SE/AM
