/**

* This test ensures that onBeforeRequest is dispatched for webRequest loads that
|
|
* are blocked by tracking protection. It sets up a page with a third-party script
|
|
* resource on it that is blocked by TP, and sets up an onBeforeRequest listener
|
|
* which waits to be notified about that resource. The test would time out if the
|
|
* onBeforeRequest listener isn't called dispatched before the load is canceled.
