BorderContainer flow gets broken when a DropDownButton gets added with no Menu/MenuItem children

[jonmsawyer]

For reference, see this fiddle: ​http://jsfiddle.net/vGqMN/7/ and attached HTML test case.

• Browser: Firefox 3.6.24, Chrome 15.0.874.106
• Platform: Ubuntu Linux 10.04 LTS (2.6.32-36-server SMP x86_64 GNU/Linux)
• Steps: Create the page as shown in ​http://jsfiddle.net/vGqMN/7/
  • isDebug: true, parseOnLoad: true
  • Declarative markup only
  • Create a BorderContainer?, place a DropDownButton? in any region without any dijit children widgets and refresh the page. The flow of the BorderContainer? will break.
  • Example:

    <button id="menuButton"
            data-dojo-type="dijit.form.DropDownButton"
            data-dojo-props="title: 'The Menu'"
    >
        <span id="menu_image">Menu</span>
        <!-- Uncomment this Menu item to see correct behavior -->
        <!-- <span id="buttonMenu"
              data-dojo-type="dijit.Menu">Foo Menu</span> -->
    </button>
    

• To fix: add a dijit.Menu child element into the button
• Expected result: BorderContainer? should flow as expected with a DropDownButton? that does not have proper children
• Tested versions in which defect can be recreated: 1.6, 1.7, 1.7.1

This is expected; it's unsupported to create a DropDownButton without a drop down.
