is there a bug in internal redirect? it makes abort() of midware not work

Description

when i use internal redirect from url1 to url2, the midware of url2 can not abort. however if i use external redirect(http 302), it works as expected.

How to reproduce

package main

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

func main() {
	r := gin.Default()
	r.GET("/t1", func(c *gin.Context) {
		c.Request.URL.Path = "/t2"
		r.HandleContext(c)
		// c.Redirect(302, "/t2")
	})
	r.Use(func(c *gin.Context) {
		c.AbortWithStatusJSON(200, gin.H{"result": "mid"})
	})
	r.GET("/t2", func(c *gin.Context) {
		c.JSON(200, gin.H{"result": "t2"})
	})
	r.Run(":8090")
}

Expectations

open http://localhost:8090/t1 in browser, return 
{"result":"mid"}

Actual result

{"result":"mid"}{"result":"t2"}

Environment

- go version:1.14
- gin version (or commit ref):v1.7.4
- operating system:win10
