// While the other accessibility tests are crash-tests, this one cannot be
// authored as one. The reason is that a crash-test is complete when a onload
// is complete. The recommended strategy for supporting asynchronous testing
// is to use reftest wait. Unfortunately, reftests are not compatible with
// test-driver. The test needs to be asynchronous as unless we wait for the
// click to be handled, we are not giving the browser a chance to crash. In
// addition the lack of a wait triggers detection of a memory leak in Blink.
