Research direction

Investigate the crash when using cacheByIndexPath: method with expanded groups in FDTemplateLayoutCell. Ensure that the cell identifier is registered for reuse before the caching operation. Compare the caching and non caching code paths to identify where registration is missing. Check the library's source code for the cache implementation and review the single comment on the issue for additional context.
