74 This test measures the time taken to fire a <span class="timeoutInterval"></
span>ms DOM Timer when the page visibility is set to "visible", "hidden" and the
n back to "visible". Due to hidden page timer throttling, the timer should fire
close to <span id="alignmentInterval"></span>s when page is hidden. And it sho
uld fire close to <span class="timeoutInterval"></span>ms, when the page is visi
