In testing one of my plugins with 4.4-beta3, I found it broke because the global comment object no longer exists on the Admin Comments page. Presumably this was removed in 4.4?

The affected code is here:
The global $comment in question is on line 41. When $comment is used on line 44, it throws a "Notice: Trying to get property of non-object" message.

@wonderboymusic want me to search the plugin directory for possible issues where folks are calling the $comment global where it will no longer be available?

In 35674:

List Tables: because we can never eradicate the existence of globals, ensure that $comment is hoisted into the global space inside WP_Comments_List_Table::single_row().

Fixes #34654.
