fixes issue #1344

I confirm that the pull-request:

• [x] Follows the contribution guidelines
• [ ] Is based on my own work
• [x] Is in compliance with my employer

It was originally posted by @cwuethrich at #1345, but has some conflicts. I've cherry-pick his commit (author is preserved). And add a test with the issue that I could reproduce with coverlet.console. Which is not required to be installed, so test is inconclusive 😞.

Thank you @cwuethrich for actual fix.
