LayoutTests/fast/events/key-events-in-frame.html

<div>
    This tests that key events targeting a frame do not propagate up the frame tree.  This will only produce output if the test fails.
    <br />
    To test manually click in the empty frame and press any key. If you receive any output the test has failed.
