Cannot use Astroquery as a source with `pytest-cov`

This may be more of an upstream issue, but I can't use `pytest-cov` with an internal test suite we have running at MAST. Using `coverage` directly works, but I want to use `pytest-xdist`, which requires `pytest-cov` and doesn't work correctly with `coverage`.

[test_minimal.py](https://github.com/user-attachments/files/29059123/test_minimal.py)

I run the above test file with this command:
`pytest --cov=astroquery.mast tests/test_minimal.py`

The versions I have in my environment are:

- Python = 3.12
- pytest = 9.1.0
- pytest-cov = 7.1.0
- coverage = 7.14.1
- astroquery = 0.4.11 (or installed from GH)
- astropy = 7.2.0
- numpy = 1.26.4

The traceback I get is:
```

```

Start by running the attached tests/test_minimal.py with `pytest --cov=astroquery.mast tests/test_minimal.py` using the reported package versions, then compare it with direct coverage and pytest-xdist. Trace the interaction around the Astropy logger traceback to determine whether the failure belongs in astroquery or an upstream dependency. Done means the owning project and a reproducible minimal case are identified, with a fix or clear upstream report.
