Go html/template 过滤 script 里的注释？！

又做了一些测试

1. 这个问题只发现于Gin里使用两个文件保存模板
2. 手动破坏template里的isComment函数可以使返回结果正常
3. 更新到Go1.14没有变化

简化后的代码

//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"}}
