 // This test doesn't makes sense in --use-cross-process-frames-for-guests, since
 // it tests that events forwarded from the embedder are properly transformed,
 // and in oopif-mode the events are sent directly to the child process without
 // the forwarding code path (relying on surface-based hittesting).
