[wish] Add scrollbar to Combobox, rather than scroll buttons only.
Submitted by tvs..@..il.com
Currently, when a ComboBox is too large to fit the screen two scroll buttons allows the user to see additional items. However, for the following use-cases, this is less than optimal:
- Alice wants to know how many more items there are, but there is no visual indication.
- Bob knows the item he is interested in is around 2/3 of the way down the list. Currently, he cannot jump there directly.
- Joe is not quite proficient at using the mouse and has trouble moving away from the scroll button at the right time, so he always misses his desired option.
