Accessing SingleEmailMessage's getFileAttachments() list

After I create a SingleEmailMessage and send it, I can get various attributes of the email - for example, its plainTextBody, htmlBody, etc., but when I look at its getFileAttachments() or getDocumentAttachments() lists, they're always null, even when the email that's actually sent includes attachments. 

Here's the code:
Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();
Messaging.sendEmail(new List<Messaging.SingleEmailMessage>{email});

System.debug('===== email.getHtmlBody() = ' + email.getHtmlBody().left(20));
System.debug('===== email.getDocumentAttachments() = ' + email.getDocumentAttachments());
System.debug('===== email.getFileAttachments() = ' + email.getFileAttachments());
The System.debug()s show me:
===== email.getHtmlBody() = <style>p{margin-top:
===== email.getDocumentAttachments() = null
===== email.getFileAttachments() = null

When I receive the email, it does have an attachment, the file attachment that the email template defines.

Is there any way to get getFileAttachments() to return the attachments?
