gjson.Json在继承的结构体中使用gconv.Scan转换后会导致值丢失，其他类型正常

gf version：v2.2.5

代码如下：

package main

import (
	"github.com/gogf/gf/v2/encoding/gjson"
	"github.com/gogf/gf/v2/frame/g"
	"github.com/gogf/gf/v2/os/gctx"
	"github.com/gogf/gf/v2/os/gtime"
	"github.com/gogf/gf/v2/util/gconv"
)

type Inherit struct {
	Id        int64       `json:"id"          description:"Id"`
	Flag      *gjson.Json `json:"flag"        description:"标签"`
	Title     string      `json:"title"       description:"标题"`
	CreatedAt *gtime.Time `json:"createdAt"   description:"创建时间"`
}

type Test1 struct {
	Inherit
}
type Test2 struct {
	Inherit
}

func main() {
	var (
		A1 Test1
		A2 Test2
	)

	A1 = Test1{
		Inherit{
			Id:        2,
			Flag:      gjson.New("[\"1\", \"2\"]"),
			Title:     "测试",
			CreatedAt: gtime.Now(),
		},
	}
	g.DumpWithType("A1", A1)

	if err := gconv.Scan(A1, &A2); err != nil {
		g.Log().Warningf(gctx.New(), "err:%v", err)
		return
	}
	g.DumpWithType("A2", A2)
}

运行结果：

./\test.exe 
build running pid: 14508
string(2) "A1"
main.Test1(4) {                                      
    Id:        int64(2),                             
    Flag:      *gjson.Json(13) "[\"1\",\"2\"]",      
    Title:     string(6) "测试",                     
    CreatedAt: *gtime.Time(19) "2022-12-30 09:49:53",
}
string(2) "A2"
main.Test2(4) {
    Id:        int64(2),
    Flag:      *gjson.Json(4) "null",
    Title:     string(6) "测试",
    CreatedAt: *gtime.Time(19) "2022-12-30 09:49:53",
}
