DeprecationWarning: Module globals; __loader__ != __spec__.loader on 3.15 #2208

Describe the bug
When I use coverage, pytest, and traceback.print_stack() together, I get a deprecation warning on 3.15. I'm not convinced it's coverage's fault, but opening here first.

To Reproduce

x.py:

import traceback

traceback.print_stack()

Now run coverage run -m pytest x.py (after pip install coverage pytest). Note that the pytest part and the coverage part is necessary, if it's missing either things work correctly. You should see something like this:

1. What version of Python are you using? 3.15.0a6
2. What version of coverage.py shows the problem? The output of coverage debug sys is helpful. 7.14.1
3. What versions of what packages do you have installed? The output of pip freeze is helpful. pytest==9.0.3 also
4. What code shows the problem? Give us a specific commit of a specific repo that we can check out. If you've already worked around the problem, please provide a commit before that fix. x.py above
5. What commands should we run to reproduce the problem? Be specific. Include everything, even git clone, pip install, and so on. Explain like we're five! command given above.

Expected behavior
No deprecation warning.
