Steps to reprouce:
- Deploy Mentions Portlet
- Deploy Notifications Portlet
- Create a 2nd user
- Add Blogs Portlet
- Add Blogs Entry, publish entry.
- Change view permissions on blogs entry, make it so only the owner has permissions to the entry.
- Add Blogs Comment, mention the 2nd user
- login as 2nd user
- Attempt to view the post.
There should be feedback somewhere that the user doesn't have permisions, it might be most logical to warn the user making the mention that permissions will block the mentioned person from viewing the content.
No feedback that the mentioned user doesn't have permissions, mentions works normally, 2nd user is unable to view asset and it is unclear why.
