Hi @victorcatn
Thanks for the PR. I will take a look at it. Is there a way to add a test to maintain the same coverage percentage?

Hi everyone, thanks once again for the support. I have released version 16.1.1 which fixes this issue. Please give it a look and don't hesitate to create a new issue or PR is something else is missing.
