Group’s stream item with one photo doesn’t display comments

Hello. May be this issue related with This onr but:

There is a stream item in group with one photo. In some reason it doesn’t display any comments:

Navigate to post and Try to open photo in popup.
Result: only popup display comments.
Expected result: Stream item should display comments too.

Thanks.
