Some tests are failing under certain conditions

[keithchev]

I incidentally noticed that a few tests are failing on python >= 3.10 when using uv as an environment manager.

Here's what I did:

• migrate pyproject.toml to use uv using uvx migrate-to-uv
• delete the uv.lock file that this command produced b/c it is broken.
• run uv venv -p 3.12 to create a new virtualenv with python 3.12.
• run uv run pytest (this automatically installs dependencies).

The failures are shown below. I unfortunately cannot reproduce these when using our "official" poetry-based approach described in the README (with Python 3.12 instead of 3.9).
