Description

When I use backticks to create preformatted code snippets, and the content is empty, then the syntax highlighing messes up.

Steps to Reproduce

1. Insert two consecutive backticks in a GitHub flavored Markdown file.

Expected behavior:

The syntax highlighter correctly highlights the snippet as an empty inline section.

Actual behavior:

The syntax highlighter continues highlighting past the closing backtick, as if the rest of the file is an inline preformatted snippet, until a third backtick is found.

Reproduces how often:

100%

Thanks for the report and for using the issue template 👍 Just to clarify, I assume you're referring to the syntax highlighting in the editor and not how things look in Markdown Preview (preview seems to render things ok with the empty code span)?

[mcandre]

I am referring to the syntax highlighting in the editor. I have not checked how the preview pane behaves for this edge case.

Thanks for confirming 👍 This package is for Markdown Preview, the Markdown syntax highlighting is provided by https://github.com/atom/language-gfm so I'll move this over since I didn't find an issue that seems to report this (though I might have missed it or it's already covered by an existing issue).

Thanks again - I thought this was reported before but couldn't quite find an exact duplicate. Reproduced on 1.35.1 with macOS 10.12.6 with:
