Thanks for the PR. Could you please have a look at the failing tests? Additionally, please keep the changes to the minimum - it seems to contain unrelated changes regarding the formatting and some strange ones regarding the tests.

Out of interest: Is there any actual error you observed or a related issue which lead to this PR?
