Research direction
Investigate the Sticky component in the Semantic UI React source to understand how it handles overflow when sticky content exceeds viewport height. Compare the implementation with the original Semantic UI library, which works correctly. Look for differences in CSS styling, overflow properties, or JavaScript logic that might cause the incorrect scrolling behavior. The issue is reproducible at the provided testcase URL.
