<p>This tests to make sure that a drag-selecting through a -webkit-user-select:ignore region works.  The selection should end somewhere inside the word 'World' below.</p>
<div><span id="start">Hello</span> <span id="end" style="-webkit-user-select:ignore;">World</span></div>

<script>
if (window.testRunner) {
    start = document.getElementById("start");
    end = document.getElementById("end");

    x = start.offsetParent.offsetLeft + start.offsetLeft - 5;
    y = start.offsetParent.offsetTop + start.offsetTop + start.offsetHeight / 2;
    
    eventSender.mouseMoveTo(x, y);
    eventSender.mouseDown();
    
    eventSender.mouseMoveTo(x + 10, y);
    eventSender.mouseMoveTo(x + 20, y);
    eventSender.mouseMoveTo(x + 30, y);
    
    x = end.offsetParent.offsetLeft + end.offsetLeft + end.offsetWidth / 2;
    y = end.offsetParent.offsetTop + end.offsetTop + end.offsetHeight / 2;
    
    eventSender.mouseMoveTo(x, y);
    eventSender.mouseUp();
