  11 <p>This test ensures WebKit can place caret after the line even when the line-height is smaller than a line.
  12 To manually test, click inside the black box outside the red box.
  13 The caret should be placed at the end of "hello".</p>
  14 <p>Also test that when you click in the red box above or below the black box, caret is placed at where you clicked.</p>
