* visit() already does a wait_for_page()
* wait_for_page() already asserts on is_browser_on_page(), as it will raise a BrokenPromise after polling
* don't use is_browser_on_page() in an assertion unless you are 100% certain you're already on the page
* if an action takes you to another page, synchronize with a wait_for_page() for that new page
