[mvdan]

What is the URL of the page with the issue?

https://pkg.go.dev/cuelang.org/go/[email protected]#Context

What did you do?

Use the plural form of a type with a doc link, i.e. CUE [Value]s above.

What did you see happen?

The doc link does not seem to work on pkg.go.dev, even though it works fine with go-to-definition on gopls.

What did you expect to see?

The doc link should be linkified. Other uses without the "s" plural suffix work fine, e.g: https://pkg.go.dev/cuelang.org/go/[email protected]#Instance
