title: Making a Listbox fill available space while still maintaining scrollbars
body: <p>The behaviour of a listbox when its width or height is set to auto is to not produce any scrollbars as it will attempt to endlessly grow within its container.</p>
  
  <p>Is there any way to have a Listbox that will resize to the space available within the container it resides within while still displaying scrollbars for content that would be beyond these boundaries?</p>
  
  <p>My application is not of a fixed size so I can't rely on setting fixed values for the Listbox or its container.</p>
