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 1472476516.1 1472476516.5 1472476516.8 1472476517 1472476517.2 1472476517.2
