style(tests): collapse extra blank lines after the new tests (E303)

The two tests added by this PR were each followed by three blank lines
before the next top-level def; PEP8/ruff E303 allows at most two. The
repo's ruff config does not enable E3 today so this is latent, but it
would surface under a stricter lint gate.
