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