			The test was doing a navigation from about:blank to an example.com URL in a ContentTask, which I guess was going bad with fission enabled since we were creating a new content process. I don't think there was a good reason to do that, so we start the test directly with the "final" URL. And since about:blank page can be special, we use a data url instead. A few `info` calls are added to have better logs, and the test is slightly refactored to be easier to follow. Finally, the test was a bit loose, only checking the number of events we were receiving. We take this opportunity to really check that we get the events that are expected. Differential Revision: https://phabricator.services.mozilla.com/D109278
