can remove h5?

I tested writing html code as below:

// Header: <a href="google.com">Link to preview</a> Some random text
package main

import (
	"fmt"
)

func main() {
	fmt.Println("Let's Go....")
}

and it is working fine I get the a tag in dom. So, I don't think there's a need for a default h5. Since the user can add whatever element they want in the comment only. Please consider removing it.
