There’s two reviews now on a deck of mine which show “Comment from author before post was edited”, but best I can recall, these user reviews still read exactly the same as before.
Ofc that can also mean they just hit “Update” without actually changing their reviews (in which case I’d suggest not having AnkiWeb mark it as such) or reverted back, but I’d just like to ask in case this is really a bug that has the updated text never overwrite the old one.
