This works: https://sourcegraph.com/github.com/sourcegraph/sourcegraph@1fe3199/-/blob/internal/codeintel/dependencies/internal/store/store.go?L53:17#tab=implementations_go

This doesn't: https://sourcegraph.com/github.com/sourcegraph/sourcegraph@1fe319919c52d420f44e763f622644d4718e5e5f/-/blob/internal/database/global_state.go?L45:28#tab=implementations_go

Both have precise code intel.
