@lucasmr I've created a new PR with your changes. Unfortunately, I could not fix this PR to keep your authorship as I could not figure out your valid e-mail-address, which is required for the sign-off.

If you prefer to fix this PR, please let us know quickly. Otherwise we'll go ahead with the new PR to get the issue closed.
