Mirroring my note from https://en.wikipedia.org/wiki/Wikipedia:VisualEditor/Feedback

In https://en.wikipedia.org/w/index.php?title=Draft:Solar_do_Ribeirinho&diff=next&oldid=861082060, a new user tried to leave me a reply to my review comment on a new draft. They left a note on my talk page expressing confusion as to why the comment they left for me wasn't visible.

The answer is, of course, that Insert/Comment generates an HTML comment. It's not at all surprising that a new user would find that confusing. I realize Visual Editor is a general-purpose tool, not a review-specific tool, but it's still a confusing user experience. It would be nice if there was some way to make this less confusing for new users.
