Fix inconsistent playwright test (#461)

* Remove sleep fixture

Playwright has a built-in "slowmo" feature that would be easiest to use.
https://playwright.dev/python/docs/test-runners#cli-arguments

* Use standard python comparison operator

The `to_equal` doesn't seem to exist in playwright for python. There is a NodeJS equivalent, but there is no supported GenericAssertion equivalent for python

https://playwright.dev/docs/api/class-genericassertions

* Add explanation to test assertion

* Fix linting issues
