Selectmenu shows behind form dialog, if initialized before dialog gets initialized

[master-of-magic]

If you initialize a select menu within a form dialog before you initialize the dialog object, the select options will be shown behind the dialog and are [partially] invisible.

A buggy code:

$("#month").selectmenu({ width: 300 }); // select menu within the dialog form
var dialog = $("#dialog-form").dialog(...);

Reproduction:

... just move line 89 in javascript to line 62, run the example and try to open the month-selectmenu

Yup, that's how the stacking logic works. Either initialize in the proper nesting order or be explicit with the appendTo option.
