Comment(by webstoc):

 I see.  Well, I don't use firebug that much; in the past when I tried it,
 I had the same cache problem with it as the fellow who filed
 [http://code.google.com/p/fbug/issues/detail?id=207 this] bug report.
 Maddening. So, I gave it a try per your suggestion, but I may not be using
 it correctly.

 I did a minor rewrite of the function, like so:
 {{{
 $('#post-preview').click(function(e){

                 //convenience function
                 function _d(msg){
                         dump(msg + "\n");
                 };

                 if ( 1 > $('#post_ID').val() && autosaveFirst ) {
                         autosaveDelayPreview = true;
                         autosave();
                         return false;
                 }
                 var myform = $('form#post');
                 _d("target: " + myform[0].target);
                 myform.attr('target', 'wp-preview');
                 _d("target: " + myform[0].target);
                 _d("submit: " + myform.submit);
                 //bind submit function
                 myform.submit(function(){
                         _d('form submitted.');
                 });
                 myform.submit();
                 myform.attr('target', '');
                 return false;
                 /*
                 $('input#wp-preview').val('dopreview');
                 $('form#post').attr('target', 'wp-
 preview').submit().attr('target', '');
                 $('input#wp-preview').val('');
                 return false;
                 */
         });
 }}}
 The output of which in the console looks like so:
 {{{
 target:
 target: wp-preview
 submit: function (a) {
     return a ? this.bind(b, a) : this.trigger(b);
 }
 form submitted.
 }}}
 So, the post-submit action of the form *is* being triggered.  In the
 firebug console however, I noted *no* action on the "Net" tab (subsequent
 to button press), implying the post is likely not actually happening, as
 you suggested.  A false return, perhaps?  That would account for the
 behavior.

 Ducking into edit-form-advanced.php, the target form is found (for me) on
 line 520.  Adding an onsubmit event here:

 {{{
 <form name="post" action="post.php" method="post" id="post"
 onsubmit='dump("foo\n");'>
 }}}
 Gives this:
 {{{
 target:
 target: wp-preview
 submit: function (a) {
     return a ? this.bind(b, a) : this.trigger(b);
 }
 form submitted.
 foo
 }}}

 I see no inline binding of submit events here, and none in post.js.  Is
 there another location that might return false?
