reflect.go's Select on Array-type Channel "$set is not a function"

package main

import "reflect"

func main() {
	ch := make(chan [2]string)

	go func() { ch <- [2]string{"Hello", "World"} }()

	rch := reflect.ValueOf(ch)
	chosen, rv, _ := reflect.Select([]reflect.SelectCase{{Dir: reflect.SelectRecv, Chan: rch}})
	switch chosen {
	case 0:
		sl := rv.Interface().([2]string)
		println(sl[0], sl[1])
	}
}

Reproduce the provided program, then inspect reflect.go:1351 and the Select path in value.go:2016 where the stack trace points. Compare array-channel handling with other reflected channel values; done means reflect.Select receives the [2]string value and the program prints Hello World without a JavaScript exception.
