Problem Definition

When utilizing mixed restrictions within a Calendar in Confluence 5.10.8, the user restricted to Editing is not able to view the calendar.

Steps to Replicate

To replicate the issue, follow the steps below:

1. With an Admin or Sys-Admin user, create a new calendar
2. Add one user to View Only Restriction within the Calendar (User A)
3. Add another user with Edit Restriction within the Calendar (User B)
4. Try to view the Calendar with User B

Expected Results

The user would be able to view the Calendar since he is the only one with permissions to edit it.

Actual Results

The User B is not able to view the Calendar. He can view the calendar only if the User A is removed from the View Restriction.

Could not find a proper workaround for the issue.
