ResizableControlBehavior sizing to 0 in initialize, why?

This line is in the ResizableControlBehavior.initialize code:

this._resizeControl(0, 0, 0, 0);

Why? It makes me do fancy things in my resize handler to avoid this call, but I'm wondering if I'm missing some intended logic here.

Any thoughts on this? It breaks the resize control in IE for divs that use CSS to get width.
It sets up the internal state and fires the initial resizing event. Why is this a problem?
In IE with a textarea that is set to width: 100% in the CSS, this results in a 0 size text area.
Have you tried nesting the TEXTAREA in a DIV similar to how the sample page does with the image example (which has width=100%, height=100%)?
