options.data ignores prototype

[dwelle]

I'm sure that v2/v3 supported data variables defined in prototype, but current verson 4.0.5 does not seem to. Nothing in release notes. Am I mistaken and it never looked into prototype?

template({}, { data: Object.create({ val: 42 }) });

// .hbs
{{@val}} // -> undefiend
