<p>This is a regression test for https://bugs.webkit.org/show_bug.cgi?id=50434. It verifies that a marquee does not animate when scrollAmount is set to 0 by script.</p>
<script>
    if (window.testRunner)
        testRunner.waitUntilDone();
    var marquee = document.createElement("marquee");
    // Sets the character color to while in order to make the image result deterministic.
    // When you want to run this test manually, change the color to black.
    marquee.style.color = "white";
    marquee.innerHTML = "Test";
    marquee.width = "100px";
    marquee.scrollDelay = 0;
    document.body.appendChild(marquee);
    setTimeout(function() {
        marquee.scrollAmount = 0;
        if (window.testRunner) {
            setTimeout(function() {
                testRunner.notifyDone();
            }, 55);
        }
    }, 0);
