Forum topic creation page loads for users with 'view only' user rights when a template is used

Steps to Reproduce

• As admin
• Go to a space where a user group has only 'view' permissions
• Create a forum
• Edit the forum page
• Edit the forum macro
• Set a 'Topic template' (create a new sample template first if needed)
• Save the page
• As a user of the group which has only 'view' permissions
• Go to the forum
• Click '+ New Topic'

Expected Result

Restricted access page is displayed

Actual Result

The page creation window opens, allowing the user to enter page title, content, etc.

NOTE

While the page creation window appears, the page cannot be saved so the topic cannot actually be created (a session error appears when attempting this).

Also note that Synchrony (Collaborative Editing) should be disabled for the page creation to load. With this enabled, the restricted access page still does not appear, and instead a spinner appears indefinitely.
