YAML frontmatter breaks syntax for Markdown body

[sheriferson]

Apologies if I missed an issue or configuration that handles this. I looked around but couldn't find anything.

I'm finding that having YAML frontmatter in a .md file breaks the syntax highlighting and formatting for the Markdown body.

Here are two screenshots that demonstrate this:

The syntax in the second screenshot is what I would expect. Link in a different color from body, "YAML" in bold, etc.

filetype is pandoc. I also tried :set filetype=pandoc.markdown, but it didn't change anything.

I have both vim-pandoc and vim-pandoc-syntax installed, and these are the only pandoc settings I have in init.vim

" ## vim-pandoc
let g:pandoc#folding#fdc = 0
let g:pandoc#spell#enabled = 0
let g:pandoc#syntax#codeblocks#embeds#langs = ['yaml', 'sh', 'html', 'sql', 'python', 'fish']
let g:pandoc#syntax#conceal#urls = 1

Is this expected behavior? Or is there a way to get proper highlighting for both the YAML and Markdown portions?

I discovered a hidden space that caused the issue. Here is the text that broke highlighting:

---
title: "sample markdown"
author: "sherif"
--- 

This post should [demonstrate][] how having **YAML** frontmatter breaks the formatting of Markdown body.

There is a space after the three dashes that close the YAML block - i.e., it's actually --- instead of ---. If I remove the trailing space the Markdown highlighting goes back to normal.

My apologies for the spurious report. I don't know if this is still considered some kind of bug (if you want the syntax to handle possible trailing spaces), but if not, I'm happy to close the issue.

Thanks for the update. Lets leave it open until we know for sure how we want to handle this. My first instinct is to say this is actually a bug in Pandoc upstream because YAML document delimiters should not allow spurious spaces, but if Pandoc is going to parse them then we should probably highlight as close to the way it parses as we can.
