// This test makes sure that a few of aspects of autofill are correctly
// preserved:
//
// * Autofill should preserve the user's case.  If you type ExA, it should be
//   autofilled to ExAmple.com/, not example.com/.
// * When you key down and then back up to the autofill result, autofill should
//   be restored, with the text selection and the user's case both preserved.
// * When you key down/up so that no result is selected, the value that the
//   user typed to trigger autofill should be restored in the input.
