Finding and fixing mistakes is the normal review process, and not
every addressed comment needs to be reflected in the tags, even if the
contributor sent it as a separate patch. Adding 'Suggested-by' to the
entire patch falsely implies that the author of the bugfix suggested
the entire work, which is not desirable either.

In this case, the bugfix is a well-known anti-pattern which is not
specific to the introduced code. I don't think this warrants a tag
tbh.
