/**
 * Test for Bug 1109146.
 * The tests opens a new tab and alt + clicks to download files
 * and confirms those files are on the download list.
 *
 * The difference between this and the test "browser_contentAreaClick.js" is that
 * the code path in e10s uses the ClickHandler actor instead of browser.js::contentAreaClick() util.
