This may have originally made sense as a class that managed the
browser state, but it has since turned into a dumping ground for
mostly pure functions that don’t make sense to instantiate.

The only downside of this is that it makes it harder to control the
order of these tests; which isn't that important. And the structure
of naming each with its test order fundamentally requires renaming
files when adding/deleting tests, so if we want to control the default
test order, we'd be better off doing that by just hardcoding a list in
the test runner code.
