Issue Summary

Currently, Confluence Team Calendars treats View and Edit restrictions as two completely independent allowlists. If a user is added to the Edit restriction but not the View restriction, they cannot see the calendar at all — even though they have edit rights.

This is documented behaviour: “Only the people listed under These people can view this calendar … will be able to see the calendar.” -> https://confluence.atlassian.com/conf92/restrict-a-calendar-1477576642.html

Reference issue: CONFSERVER-52807 (reported as a bug, but behaviour aligns with documentation -> https://jira.atlassian.com/browse/CONFSERVER-52807

Steps to Reproduce

1. Admin creates a calendar.
2. Admin adds User A to the View restriction.
3. Admin adds User B to the Edit restriction (but NOT to View).
4. User B tries to access the calendar.

Expected Results

User B can view the calendar (edit implies view).

Actual Results

User B cannot see the calendar at all.

Workaround

1. Add all editors to the View restriction as well, ideally via a shared group
2. If all users already have View access to the related space, they can be removed from the View Restrictions tab. By default, anyone with space-level View permission will then be able to see the calendar, and that way only the Edit tab needs to be managed.
