Problem
Currently when "by_title" chunking strategy is used and coordinates = true parameter is set (in order to return coordinates of the PDF chunks), coordinates are not returned (because in this strategy separate chunks are joined under the hood, which may span multiple pages).
"by_title" strategy is really useful because "default" strategy often returns really small chunks (containing one word or a couple of words). Therefore, inability to use coordinates with "by_title" strategy blocks use cases which require coordinates of text blocks in PDF files.
Suggestion
The suggestion is to return consolidated bounding box coordinates when "by_title" chunking strategy is used, returning a rectangle with extreme coordinates of the included chunks if multipage_sections = False parameter is passed (therefore chunks cannot span multiple pages and Unstructured.io API can calculate bounding box coordinates on the single page).
Additional context
The issue was discussed here: #1698
