When calling MakeWrapper on a struct containing embedded structs, only methods on the top-level struct are exposed in the resulting js.Object

Example

package main

import (
	"fmt"

	"github.com/gopherjs/gopherjs/js"
)

func main() {
	js.Global.Set("Example", map[string]interface{}{
		"New": New,
	})
}

type A struct{}

func (a A) MethodA() {
	fmt.Println("A")
}

type B struct {
	A
}

func (b B) MethodB() {
	fmt.Println("B")
}

func New() *js.Object {
	return js.MakeWrapper(B{A{}})
}

In Go, it'd be fine to call B{A{}}}.MethodA(), but the resulting js.Object only has MethodB.

I did some searching around, but couldn't find any other issues/references to why this is the case.
