[BUG] Failing test for the (handlebars) partial helper using properties

I'm trying to set the name of a partial as a property on a view, so that I can extend that view changing the name of the partial (thus rendering a different one) and there seems to be a bug on the partial helper by which the helper is trying to render a partial with the path of the property.

I think this isn't expected behaviour because you can use properties on other helpers like the view helper and they are accessed correctly.
