Source maps do not match the right (non-spec) files

[sroucheray]

As described in this bug report on the Angular repo, when testing with code-coverage ng test --code-coverage, Devtools do not match the right files (for all non-spec files). So I can add a breakpoint in any *.spec.ts, but then when I step into the tested file the cursor is not at the right position within the file. It also mean I can't add breakpoint in non spec files.

I'm also seeing this on an angular 9 project. What's strange is this is one of many projects but this is the only one where we see the issue as far as I know, so I'm still not sure it's the fault of coverage-istanbul-loader.
