title: Unable to type in second Telerik RadComboBox
body: <p>I have a page with five RadComboBoxes on them. When the page loads I am able to click inside any of them which begins to search the contents of the combo box.</p>
  
  <p>If I select an option from the dropdown list (regardless of whether or not I narrow the search by typing), I am left unable to type within one of the other four RadComboBoxes unless I click out of the box and back in again - I can however select an item from the dropdown as usual.</p>
  
  <p>Alternatively, if type in the first box without actually selecting an item, and then click in another RadComboBox I am able to type to search.</p>
