Came here looking for a similar solution. As a workaround:
1) Set your Alfred snippet up as markdown
2) Install Markdown Here extension for Chrome - https://chrome.google.com/webstore/detail/markdown-here/elifhakcjgalahccnjkneoccemfahfoa?hl=en
3) Paste your snippet, select it and hit 'Toggle Markdown'.
It's an extra step, but at least it all happens inline.
