Go HTML/template 会莫名吃掉一些字符？（过滤 script 里的注释？）

代码是这样的：

//Go 1.14 amd64 win10
package main

import (
    "github.com/gin-gonic/gin"
    "net/http"
)

func main() {
    r := gin.Default()
    r.Static("/assets", "./assets")
    r.LoadHTMLGlob("tmpl/*")
    r.GET("/test", func(ctx *gin.Context) {
        ctx.HTML(http.StatusOK, "test.tmpl", map[string]interface{}{})
    })
    if err := r.Run(); err != nil {
        panic(err)
    }
}

<!-- test.tmpl -->
<!doctype html>
<html lang="zh-cn">
<head>
    {{template "head"}}
</head>
<body>
{{template "foot"}}
</body>
</html>

<!-- base.tmpl -->
{{define "head"}}
    <meta charset="UTF-8">
    <!-- bulabula... -->
{{end}}
{{define "foot"}}
