Markdown include not stripping YAML front matter #1129

Bug Report

Steps to reproduce

1. Create a Markdown Page to view
2. Create a markdown page to include with a YAML header.
3. Add a link with the include tag to the page.
4. View the markdown page with the link and when the link I parsed the YAML header is also pulled through and rendered as markdown putting a line on the page followed by the YAML header information as test and then another line.

What is current behaviour

When the link I parsed the YAML header is also pulled through and rendered as markdown putting a line on the page followed by the YAML header information as test and then another line.

What is the expected behaviour

The markdown is rendered from the include should only have the markdown rendered and not the YAML front matter.
