Zubin pushed to branch wip/9.12.3-backports at Glasgow Haskell Compiler / GHC Commits: 351ad869 by Ryan Hendrickson at 2025-09-17T12:54:08+05:30 haddock: Document instances from other packages When attaching instances to `Interface`s, it isn't enough just to look for instances in the list of `Interface`s being processed. We also need to look in the modules on which they depend, including those outside of this package. Fixes #25147. Fixes #26079.
