New message preview is not at top

If message preview is enabled (F7) and an unread email is selected, that email is not always displayed starting at the top/beginning of the email.

It *appears* that the preview position of an unread email may be related to the scrolled position of the previously viewed email . The expected/intuitive behavior when previewing an unread email would to show the beginning of the email .

The behavior of remembering the scrolled position of a previously viewed email is nice, especially if it's long, and would be nice to keep that behavior.
