<select> elements shows empty texts in IE 7.0.5730.11IC and IE 6.0

Issue Summary

When the function Drupal.jsAS.prototype.populate is called in activeselect.js it populates right the element, but in IE the texts are shown empty.

To make a quick fix i did:
var opt = new Option(text, value, false, selected);
opt.innerText = text;
$(this.targets[targetIndex]).append(opt);

Where before was:
$(this.targets[targetIndex]).append(new Option(text, value, false, selected));

And works correctly in Firefox, IE 6 and IE 7
