What version of Go are you using (go version)?

$ go version
go version go1.19 linux/amd64
$ gopls version
golang.org/x/tools/gopls v0.9.4
    golang.org/x/tools/gopls@v0.9.4 h1:YhHOxVi++ILnY+QnH9FGtRKZZrunSaR7OW8/dCp7bBk=

Does this issue reproduce with the latest release?

Yes

What operating system and processor architecture are you using (go env)?

GOHOSTARCH="amd64"
GOHOSTOS="linux"

What did you do?

Open a main.go file and try autofilling these structs:

package main

type GenericUser[T any] struct {
	Name  string
	Age   int
	Value T
}

type StructUsingAGeneric struct {
	User GenericUser[string]
	Age  int
}

func main() {
	// Fill anonymous struct breaks here.
	_ = GenericUser[string]{
	}

	// Here it isn't even an option.
	_ = StructUsingAGeneric{
		
	}
}

What did you expect to see?

I did expect gopls to autofill these structs without problem when the generic type is provided.

package main

type GenericUser[T any] struct {
	Name  string
	Age   int
	Value T
}

type StructUsingAGeneric struct {
	User GenericUser[string]
	Age  int
}

func main() {
	// Fill anonymous struct breaks here.
	_ = GenericUser[string]{
		Age: 0,
		Value: "",
	}

	// Here it isn't even an option.
	_ = StructUsingAGeneric{
		User: GenericUser[string]{},
		Age: 0,
	}
}

What did you see instead?

Error on the first case in my lsp client, no action suggested in the other case.
