title: Error when using mailto: link in Mobile Safari in app-capable mode
body: <p>I've got a form in a web page with an action that is "mailto:email" (where email is a real email address). When I load this page in Mobile Safari in regular mode (ie, not launched from home screen with app-capable mode), this works fine - after I submit the form, the email app comes up.  However, when I'm in app-capable mode and have launched from the home screen (so, no Safari chrome), and submit the form I get the error "URL can't be shown". However, a regular mailto: link (ie, not in a form) <em>does</em> work when in app-capable mode.</p>
  
  <p>Has anyone else noticed this? Any workarounds? Are forms disallowed in app-capable mode?</p>
  
  <p>Thanks,</p>
