UFD event propagation demonstration page

the master select tag: inside UFD

This is a normal select-dropdown. The log to the right shows events when fired. Try changing the value ...

The UFD widget can be initialized and destroyed without disturbing these event handlers, and events can be bound and removed independant to UFD. When a select is wrapped, UFD triggers some but not all, events on the original: namely the focus, change and blur events. Initialize the UFD, then try changing the value again.
