Notifications templates as Wiki Components are not loaded at startup

Steps to reproduce:

• Install the Blog Application (>=9.6)
• In your notification settings:
  • enable notifications for blog
  • enable notifications for your own event
• Edit (with the object editor) the page: Blog.BlogNotifications
  • in the field Notification template, add a line on the beginning with: <p>This is a test</p>
• Publish a blog post
• Look at your notifications, you should see something like:
  
• Now restart your wiki, and look at the notifications:
  
  The default template is used, so it means the object in Blog.BlogNotifications has not been loaded, so I suspect Wiki Components to be the cause of that, but maybe it comes from a notifications component.
