This can add cost and latency to the change author and distracts them from the project at hand. And because it costs the reviewer basically nothing to say, "While you are in there....", it slows the original author's work.

Even worse, if there are enough of these minor changes, some other reviewer may take issue with their "small, focused changes" preference, and ask you to split it.

This is why Google has the "It doesn't have to be perfect; it just needs to be better" standard: So reviewers can't impose undue costs on authors.
