Resource Raith, Charles, II. The Gospel of John: Theological-Ecumenical Readings. Eugene, Oregon: Cascade Books, 2017. has some unusual links:
1. verse 4444424 which it does translate for mouse over ...

2. or this one where the mouse over shows more references than the link:

3. on footnotes it seems to not know when to quit - providing 2 footnotes for a single reference

Entertaining, yes; inspiring confidence, not so much. I expect a rather obvious relationship between scripture references and their mouse-over rendition.
