Is it possible to marshal map[string]string with multiline strings?

[tgf9]

I have this code.

package main

import (
	"log"
	"os"

	toml "github.com/pelletier/go-toml/v2"
)

type Foo struct {
	Data map[string]string `toml:"data,multiline"`
}

func main() {
	f := Foo{
		Data: map[string]string{
			"one": "hello\nworld",
		},
	}

	enc := toml.NewEncoder(os.Stdout)
	enc.SetArraysMultiline(true)

	if err := enc.Encode(f); err != nil {
		log.Fatalln(err)
	}
}

I expected this:

$ go run main.go 
[data]
one = """
hello
world"""

But, instead I got this:

$ go run main.go 
[data]
one = "hello\nworld"

Is there a way to print the map values as multi-line TOML strings?
