title: Prevent scrolling when mouse enters WPF ComboBox dropdown
body: <p>When a <code>ComboBox</code> has a large number of items, its dropdown will become scrollable. When the user invokes this dropdown, and moves the mouse cursor to enter the bounds of the dropdown from the bottom, the dropdown immediately scrolls one or more items down the list (<em>from goobering: also happens when exiting the bounds via the bottom edge</em>).</p>
  
  <p>This scrolling is not intuitive, as the list does not scroll upwards when entering the bounds from the top.</p>
  
  <p>How can we disable the automatic scrolling behavior?</p>
  
  <p>In Visual Studio this behavior can be observed via the member dropdown on the code editor's navigation bar (<kbd>CTRL</kbd>+<kbd>F2</kbd>).</p>
