This tests the delay between when you type and the search event fires. As of this writing we can't use DOM events to type into a search field, so the test uses the event sender and only runs under DumpRenderTree. The two rows below should match. 0.5 0.4 0.3 0.2 0.2 0 1472474054.3 1472474054.7 1472474055 1472474055.3 1472474055.5 1472474055.5
