Can't open the original file for coverage view

[AdrianCert]

Type: Bug

Behaviour

When I run coverage I can see the origianal file. I received a miss file windows. My assumption is that the mapping is not do correctly.
I runned over test with coverage of this repo https://github.com/pypa/virtualenv

Steps to reproduce:

1. clone https://github.com/pypa/virtualenv
2. install all deps needed

uv sync --all-group --all-extras
uv pip install pytest-cov # this is need to the feature to work (not provided by the repo deps)

3. Configure as pytest with test directory and run test with coverage
4. On the Test Coverage window any file listen will not be accesible

Diagnostic data

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)
