BUG: DropDown with filter does not select item when only 1 available

This is reproducible on the demo site.

Using the "DropDown with custom filter operator" on this page https://blazor.radzen.com/dropdown

  1. Select "Ana Trujillo Emparedados y helados" with the mouse
  2. Click in the filter and type "alfr"
  3. If you now try to push the down arrow to select "Alfred" it will not work

Another variation on the same thing is

  1. With the dropdown clear and no filter
  2. Type "ana" then hit down and enter... The value is correctly selected
  3. Now click the filter again, delete "ana" and type "alf" then push down arrow (which visible works) and hit enter to select Alfred... nothing happens and the value does not change...
