... and laws/tests :)

Slipped a fix in here, but probably deserves its own PR: https://github.com/typelevel/cats-effect/pull/2545/commits/bdc7429e6b333500a07d357b7dbe783f34aeee26#diff-5acd9e5b3bc8897d205aa4590f18c307679d41279ca72a125764900fffe9d568

Removing this from the milestone because it is not a blocker and the fix is part of another PR.

The fix went through in https://github.com/typelevel/cats-effect/pull/2545, but we are still lacking laws/tests.

Let's leave this issue open to track the lack of tests
