The "Invision HTML Template" syntax hihglithing for code boxes doesn't work out side of editors

As per title. When you post content that includes a code box set to use the Invision HTML Template language, the syntax highlighting works in the editor but shows nothing after it's posted.

I noticed the issue after editing a post with this code box in the content:

{{if \IPS\Dispatcher::checkLocation( 'front', 'cms', 'pages', 'page' ) AND \IPS\Request::i()->pagename == 'PAGE_NAME' }}
	<!-- YOUR CODE HERE -->
{{endif}}
