Allow nesting code snippet shortcodes within code snippet shortcodes

[sheabunge]

Is your feature request related to a problem? Please describe

There is currently no way to use the [code_snippet] shortcode within a HTML snippet, even with PHP and 'Evaluate additional shortcode tags' enabled.

Describe the solution you'd like

Create a HTML snippet with the following code:

[code_snippet id=42 php shortcodes]

Create a second HTML snippet that references this first snippet:

<div> [code_snippet id=1 php shortcodes] </div>

The second snippet should render the content of the first by evaluating the shortcode.

Describe alternatives you've considered
