Worth knowing before you test: this pull replaced the book details page with a new shared PublicBookDetails component (+2231 lines) and added a full checkout flow (book-cart, book-checkout). That supersedes the book-page fixes I made earlier, so it's worth checking the broken icons, hardcoded values and image zoom behave correctly in the new implementation. I can verify that against the new component if you'd like.
