Bug breaks AJAX requests from other plugins

Is there a reason that you aren’t checking for DOING_AJAX constant on line 48 of admin.php as shown in example for access control here ( https://codex.wordpress.org/Plugin_API/Action_Reference/admin_init )?

It appears to be breaking AJAX functionality in other plugins by blocking requests. The plugin that I noticed this affecting was Simple Calendar (can’t change months on calendar without being logged in as admin), but I would assume that it would break others as well.

If this is not desired functionality could you please add a check for DOING_AJAX as described in the documentation above?

Thanks
