Thank you for reaching out to us and reporting this. You are absolutely right; we dropped the ball there. The docs will be fixed for an upcoming version in this regard.
PS: To avoid confusion here, I have closed the thread, because the topic has been solved. We track issues with the to fix tag you have already added yourself to the topic. While it was correct in this case, it is usually only being applied by us when we decide that we want to fix something (and later find the thread which was the cause for the fix to announce the carried out fix).
