value with !!int64 tag becomes nil without error

[vvakame]

https://play.golang.org/p/ecNPtvSD1U-

variables := make(map[string]interface{})
err := yaml.Unmarshal([]byte("v: !!int64 1"), &variables)
if err != nil {
	panic(err)
}
fmt.Println("%#v", variables)

expected
become error. because int64 is not defined on yaml spec. https://yaml.org/spec/1.2.2/#10213-integer

actual
ignored.
