// This test makes sure that the autofill placeholder value is autofilled
// correctly.  The placeholder is a string that we immediately autofill when a
// search starts and before its first result arrives in order to prevent text
// flicker in the input.
//
// Because this test specifically checks autofill *before* searches complete, we
// can't use promiseAutocompleteResultPopup() or other helpers that wait for
// searches to complete.  Instead the test uses fireInputEvent() to trigger
// placeholder autofill and then immediately checks autofill status.

 * 3. Waits for the search to complete.
 * 4. Compares the input value to `valueAfter`. If anything is autofilled at

 * 5. Compares the placeholder to `placeholderAfter`.
