6 * Test for bug 549340.
7 * Test for browser.js::contentAreaClick() util.
8 *
9 * The test opens a new browser window, then replaces browser.js methods invoked
10 * by contentAreaClick with a mock function that tracks which methods have been
11 * called.
12 * Each sub-test synthesizes a mouse click event on links injected in content,
13 * the event is collected by a click handler that ensures that contentAreaClick
14 * correctly prevent default events, and follows the correct code path.
