title: Disable autocomplete on focus on choice items
body: <p>I am using jQuery UI Autocomplete plugin on a textarea</p>
  
  <p>What I want is the textarea content should not be modified when the user hovers on the autocomplete list</p>
  
  <p>This means, if the user scrolls though the list or hovers on the options, the textarea contents should not change. The change should occur only on selection of the option.</p>
