When you go to the next page from the first page of mailings in CiviMail, it reverses the sort order

When you click CiviMail in the left-hand nav menu and you have more than one page of mailings (this default view is scheduled and sent mailings, I believe), when you click next to go to the next page, the sort order is reversed (at least for the Completed date, which is the default sort column when we use it). This is very confusing to users.

Interestingly, if you click Scheduled & Sent Mailings first, the bug does not seem to occur, even though that's the same view (right?).
