After Hamish's suggestion. Entwine onchange would not get executed in IE8 at all, which would have the effect of the displyed dropdown selection not being set. Change to onadd also mandates the changes to onadd on other parts of the tree component - otherwise the change event can trigger before the tree elements are added to the DOM.
