issues with frontmatter metadata

[yocontra]

Just found this project and we are going to use it for a publishing tool we're working on, just noticed an issue where it seems to strip some data out of the markdown. Given this input pasted in:

---
title: This is a title of a new blog post
excerpt: This is some excerpt to show on the main list portion of our blog and should probably be maximum 3 sentences. Happy writing, good luck.

Markdown is intended to be as easy-to-read and easy-to-write as is feasible.

It produces this output: https://ipfs.io/ipfs/bafkreiebx7qcpx3iiaops52aeyl2egia4uzzmurff7n5wscugcb4w3jdlm which breaks the formatting of the metadata and makes some of it into title tags.
