Private properties prefixed with `$_` (dollar underscore) are not available inside component

See original GitHub issue

Version

2.5.16

Reproduction link

https://jsfiddle.net/jfyLx256/

Steps to reproduce

Prefix a property with $_ and try to reference it within the component or template.

What is expected?

$_ prefixed properties should be rendered in template and available within the component.

What is actually happening?

$_ props are undefined. Not rendered in template and undefined in component logic.

Private property names are described in the Vue style guide and the $_ form is officially recommended. https://vuejs.org/v2/style-guide/#Private-property-names-essential.

I first noticed this in a project built with vue-cli@3.0.0-beta.16.

@chrisvfritz do you think we should add a note about them not being proxied in the style guide?
