Backslash in code block causes markdown preview/rendering coloring issue

[schallm]

• VSCode Version: 1.23.1
• OS Version: Windows 10 (1709)

Steps to Reproduce:

1. Create Markdown file
2. Paste following text
   ```sql
   select '\' + foo from bar
   ```
3. View preview

Interestingly, this seems to be an issue in several products... Github and TFS also color this incorrectly... Do they all use the same coloring library?

select '\' + foo from bar

vs

select 'hello' + foo from bar

Does this issue occur when all extensions are disabled?: Yes

We use highlight.js inside the markdown preview for colorization. This is an upstream bug with their sql highlighter
