Bootstrap/Load: Always run the fatal error handler at shutdown, but don't display the PHP error template once headers are sent.

If a fatal error occurs midway through a page load, or in a REST API request, it still needs to be handled internally for the recovery mode, but the custom message may conflict with already rendered output, e.g. by displaying HTML markup in an XML or JSON request.
