Description
In my application stackprinter ignores the passed in supressed_paths and I am not sure why (this has already worked and I am not sure what changed).
I can't seem to create a short snippet which reproduces the error but in my application it fails every time.
This is the function where I get the traceback.
If I set a break point with the debugger I see that suppressed_paths is indeed properly populated. However if I inspect the returned lines I see the traceback with the included library files.
I have created a testcase for pytest which fails every time.
Excerpt from github actions (just open the tox part in line 12)

It would be really nice if you could check out the dev branch and run pytest on the test_wrapper.py file.
The tests need the following libraries additionally to the ones in requirements.txt:
pytest pytest-asyncio asynctest
