Normally, one can find the documentation on a playwright test fixture by finding its declaration (i.e., you can ctrl-click on the fixture name and find its documentaion). However, `mergeTests` re-declares the type, making it much harder to find the documentation on a given fixture. It's easy enough to avoid `mergeTests`: we just structure our `test.extend` calls as a strict hieirarchy.
