Quill 2's semantic HTML saves a blank line as a truly empty <p></p> (no <br> placeholder) — verified in the DB (invoice_sections hold <p></p>, zero <p><br>) — which collapses to nothing outside the editor. cleanQuillHtml (PDF path) and the new restoreQuillBlankLines (order/ invoice read-only previews) restore the placeholder at render time, so existing stored content is covered retroactively.
