dead source links in haddock of base:Data.Ord on hackage

Source link https://hackage.haskell.org/package/base-4.16.1.0/ghc-prim-0.8.0/src/GHC-Classes.html#Ord from https://hackage.haskell.org/package/base-4.16.1.0/docs/Data-Ord.html is dead.

That link is just wrong? The module is present https://hackage.haskell.org/package/ghc-prim-0.8.0/docs/GHC-Classes.html and its source links work, e.g., https://hackage.haskell.org/package/ghc-prim-0.8.0/docs/src/GHC.Classes.html#Ord

I ran into this while teaching. It actually forced me to use the "more correct" way: look up the definition of Ord in the language report.
