Problem with mailto: in form action in iPhone web app in app-capable-mode

I am developing an iPhone web app. I have a simple form whose action is "mailto:...". When I have this in the regular mode in Mobile Safari it works fine, but when I am in app-capable-mode, the form fails to invoke the email app. I *can* invoke the email app from a regular mailto: link in app-capable-mode, however (ie, just linking to it using <a href="mailto:..." ...>).

Do you know why this would be the case? Am I missing something?

Thanks!
