In the mobile site, the references widget parses the HTML of the page to generate a structured data object representing all references in the page.
When a reference is clicked it shows a "ReferencesDrawer" widget showing the user the reference in place.
Problems with existing implementation
- Rendering can be very slow
- If you visit https://en.m.wikipedia.org/wiki/Special:MobileCite/790359434 we lazy load the Notes section however this is no lazy loading of the references or further reading section. It is not clear if this is a bug or expected behaviour.
