rotation and width not working together

[thebikwirm]

upon my previous issue/question about rotation of discharger area
I have rotated the discharge, which works fine, but now I am trying to make the width wider/longer, but is not affecting tip area.

    <machine type="discharger">
        <workArea width="20" offset="-2 0.75 -0.25" raycastDistance="0.1" rotation="0 90 0"/>
    </machine>
</vehicle>
