title: Combobox autocomplete only working on some values?
body: <p>I have a combobox that is dynamically filled with datasources. The values are just number ranges (e.g. 1-50, 61-100). For some reason autocomplete doesn't always work:</p>
  
  <p>example:
  combobox is filled with 1-50
  typing in 4 shows 40,41,42...
  typing in 2 does not show 20...</p>
