Hi

If the scroll bar in a combo box is selected, then the scrolling area of the combo is hidden.


Steps to reproduce

1. hit the expander to select a value

2. try to scroll down with slider (combo box is hidden)

3. try to scroll down with keyboard (current selection not bought into view)


This gives error in IE11, but does not give error in Chrome.


Note that in <5.0.1, this error was present that seems to have been cleared up.
