Check all checkbox checks invisible comments on edit-comments.php

[mdawaffe]

The invisible comments kept in reserve for the infinite comments feature get checked when you click the check all checkbox on edit-comments.php. If you then apply some action (click approve, mark as spam, delete, ...), that action will get applied to the invisible comments also.

Attached.
