I had suggested wording for this; did you see it?  Michael?  Rob?

One client may try to create a preview out of the most feature-rich alternative (HTML); another will create a preview out of the first sequential text part it finds.  Another example would be competency in HTML -> plaintext parsing.

However, if the content is vastly different then I do think there is chances for confusion, especially for users that use previews as a way to contextually scan their mailboxes.

But it seems important enough to justify a mention since it does clean up, at best, a minor annoyance and, at worst, a real source of confusion that end-users have complained about in the past.
