Transfer throws 'Invalid Argument' in IE7 without CSS border property

In IE7, the transfer effect throws an 'Invalid Argument' error in IE7 when the CSS border property is missing or set to 'none'.

Example CSS:

.ui-effects-transfer {
    background: #090;
    border: none;
}

Note: also occurs if the border property is missing entirely.

You can use the transfer demo code on the jQuery UI website to verify the issue: http://jqueryui.com/demos/effects_general/#transfer (make sure to replace the CSS with the CSS above)
