there's an edge case in production where, due to formatting changes picked up by the crawler, the annotate page for certain services is no longer displaying the quotes, even if they still exist in the document. this adds an option to try to 'restore' the quotes by updating the quoteStart and quoteEnd of the point in question based on its new position in the document.

Thanks !
