There are several Behat steps for core_course which can have their timeout removed.

The default timeout is 6 seconds and is there to allow any JS to finish loading the page. In reality we don't need this in most of Moodle any more, and in this specific set of cases the content is already definitely loaded. Because these are in try/catch blocks we're doing it multiple times in most cases. For someone testing the affected scenarios this takes minutes off a run. Doesn't seem like much but makes the developer life much nicer.
