Can not create Merge Request by user from group not owning project but shared with it

[Mikhail Tripolitov]

My problem shortly can be described this way:

1. group1 with project1 in it, project1 has Merge Request feature enabled.
   
2. user1 is a Developer under group1 and he can see Create Merge Request button
   
3. group2 has no projects but has shared project1 with up to Master permissions
   
4. user2 is a Developer under group2 and he CAN NOT see Create Merge Request button
   

is this a bug?

Thanks,

Mikhail
