/**
* 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.
