Strange clash between range control and html edit control (Firefox only)

>
> All:
>
> We get a strange (and I think, new) error when using the range control
> and the html editor control in combination.  The error does not
> reproduce in www.orbeon.com XForms sandbox, but exists in the latest
> build.  Please see the simple test case attached.
>
> The error occurs during loading the form.  Firebug reports "FCKEditorAPI
> is not defined" at line 2598 in xforms.js (which may or may not be
> connected with the problem: my JavaScript is, to say the least, flimsy).
>  The Loading indicator stays on.  If you comment out the lines that show
> the range control, the problem goes away.
