Group ownership of Distribution Group not working

Question

Hi,
We recently migrated from Exchange 2007 to 2013 CU2. We have various security groups with permissions to edit various distribution lists; this is no longer working. I've already researched the problem and I understand two things are necessary for a
user to have permission to edit a distribution list:
1. User must have membership in the My Distribution Groups and My Distro Groups Membership roles. Already done.
2. User must be an owner of the distribution group.  
The problem comes with the ownership. I'm assigning ownership of the distribution list to a security group, of which my test user is a member. Per
this article, groups can own groups again as of 2013 CU1.
If I directly assign a user ownership of the group, they can edit membership without issue, which means item #1 is satisfied. But they are not receiving ownership by way of membership in the group that owns the distribution list. Or put another way, their
group membership is not granting them ownership of the group as it should.
Any thoughts? Spent a good hour searching and can't come up with anything.
Thanks,
James

Hi -
That is correct, and is a problem with dozens of existing distribution groups.
For testing purposes I just did the following:
1. Created a new distribution group "Test Distro Group"
2. Created a new mail-enabled security group "Test Distro Group Owners"
3. Ran Set-DistributionGroup -Identity "Test Distro Group" -ManagedBy "Test Distro Group Owners"
4. Confirmed ownership via the shell:
Get-DistributionGroup -Identity "Test Distro Group" | fl
GroupType                                 : Universal
SamAccountName                       : Test Distro Group
BypassNestedModerationEnabled  : False
ManagedBy                                 : {contoso.com/Users/Test Distro Group Owners}
5. Confirmed ownership via ECP:
6. Added a test user "_Sample Teacher" to the "Test Distro Group Owners" group. Confirmed membership via ECP:
7. Logged into OWA as "_Sample Teacher," went to Options, then Groups. "Test Distro Group Owners" is shown as a group that the user belongs to, however no groups are shown under "distribution groups I own."
8. If I add "_Sample Teacher" directly as an owner of "Test Distro Group," the group appears as expected as an owned group.
So in short...the user is a member of the security group, the security group owns distribution group; the user should then be an owner of the distro group via membership in the security group, however this is not working.
Thanks for any help you can provide. I'm not sure where to go next.
