Comment (by stephenharris):

 I've written a test which (almost) replicates this. The test unexpectedly
 passes because of changes made to the mock PHPMailer class explicitly
 designed to suppress this behaviour (see #28909).

 In my view we should be creating a new PHPMailer instance for each email,
 not trying to reset the instance for each e-mail (evidently PHPMailer
 doesn't allow us to do that).
