The select popup box stretches from the top of the screen to the bottom and there are still more options to display. The popup has arrows at the top and bottom for scrolling but it does not respond to mouse wheel scrolling even when the mouse is directly over/within the popup.

This works fine with normal Swing components or in a full web browser like Chrome. Users expect this behavior and my customer is complaining that the usability of the select component in our JavaFX WebView is unacceptable.

Here is a screenshot of the huge popup: http://imgur.com/jPPdHiq
