Steps to reproduce:

1. Implement a fragment renderer that throws an exception in the render method
2. Deploy the fragment renderer
3. Add the fragment to a content page
4. Refresh the view

Expected result: the fragment doesn't display and an error message is shown without breaking the page

Actual result: The page breaks and there's no way to revert this
