Convergence 2.1 displaying image attachments - honoring Content-Disposition

Question

Is it reasonable to assume that when displaying a message from within Convergence 2.1 that images (jpg for example) should be displayed based on the Content-Disposition header value? That is to say that if Content-Disposition is "inline" that the image shall be displayed in the body of the message and that if Content-Disposition is "attachment" the image shall not be visible until it is selected or some other action is taken?
The behavior I observe in Convergence 2.1 is that inline images are show inline and are also duplicated again in a "preview mechanism" at the the end of the message. Attached images are not displayed inline but are also visible in the preview mechanism at the end of the image.
Can this preview behavior be changed to explicitly honor Content-Disposition?
From RFC 2183 (http://www.ietf.org/rfc/rfc2183.txt)
2.1 The Inline Disposition Type
A bodypart should be marked `inline' if it is intended to be
displayed automatically upon display of the message. Inline
bodyparts should be presented in the order in which they occur,
subject to the normal semantics of multipart messages.
2.2 The Attachment Disposition Type
Bodyparts can be designated `attachment' to indicate that they are
separate from the main body of the mail message, and that their
display should not be automatic, but contingent upon some further
action of the user. The MUA might instead present the user of a
bitmap terminal with an iconic representation of the attachments, or,
on character terminals, with a list of attachments from which the
user could select for viewing or storage.
