## My post

Steps:

1. Given you have {metadata: true}
2. convert a file with the above yaml-like metadata to html (note colon in title)

Results:

The Title will return Undefined but should return title. Looks like a bug in the yaml's regEx? I tried quotes, bacticks, entities/hex/etc.... none worked.
