title: Editable ComboBox behavior on arrow navigation in drop down
body: <p>The default behavior for non-editable Combobox when you navigate through drop down list with Up and Down keys is, that the current item is highlighted but not selected. Only on Enter Key the Item gets selected.</p>
  
  <p>If you set <code>IsEditable="True"</code> then the behavior is different. Currently selected item (and or Text input) changes by keyboard navigation in the drop down.</p>
  
  <p>My problem with this is, that I'm filtering the items depending on text input. And when you select, you have one exact match and items count goes to one. </p>
  
  <p>So it's not possible to select a correct item with a keyboard.</p>
