Cannot create branch on Gerrit

Question

I am not able to create remote branches on Gerrit. The project configuration is as follows

Reference:  
refs/heads/*

Create Reference 
Owners

Reference
refs/heads/work_*

Create Reference
Owners
Developers

I'm trying to create the branch by pushing from git:

git push origin refs/heads/work_foo

But I get error 403 permission denied.

If Developers are allowed to create references, why am I not allowed to do it?

It does work if I have it like this:

refs/heads/work/*

But for other reasons I cannot have a slash in the branch name so I'd like to keep the work_* pattern.
