`WP_List_Table`'s constructor registers an `'admin_footer'` callback when AJAX is enabled. As such, if you create multiple instances of the class, you get multiple JS blobs on the page when the callbacks fire. Extra instances get made when `wp_comment_reply()` invokes the class constructor without checking for the existing instance via the `$wp_list_table` global. 

We shall check the `$wp_list_table` global in `wp_comment_reply()`.

Props sorich87.
