Previously, autocomplete was cleared before the results for the current query were retrieved. The new results would then be added when the network request completed. This resulted in a noticable flicker. The results are now updated when the request for the current query is completed. There is a small behavior change in that the query itself is no longer included in the autocomplete dropdown unless the list would otherwise be empty.
