You have obviously nailed the problem on the head. I attempted to reply to this a few times without sounding snotty, but while writing my ideas fell apart and you just can't say "Conversions don't cause spelling errors" without saying why the user was seeing what s/he was seeing. I feel much better now that the mystery is solved.
@dawnybros I link to some interesting posts about the origin of Topaz in
this old post.
