Decoration for code span containing backtick is broken

What is the problem?

Look at this markdown below:

```a`a```

This markdown text should be converted like below HTML

<code>a`a</code>

a`a

markdown-it recognize this correctly.

However, vscode-markdown recognize like below:

``<code>a</code>`a```

As a result, in editor view, decoration rectangle drawing result is strange.

How can I reproduce it?

1. "markdown.extension.syntax.decorations": true
2. create new markdown file
3. paste

```a`a```

Environment

• Windows 10 Home 1809
• Visual Studio Code 1.31.0 or later
• Markdown All in One 2.1.1

I have disabled decorations in the fenced code blocks. However, I didn’t touch the indented code blocks. There are many corner cases if we want to perfectly determine the indented code blocks. I don’t think it is worth that effort.

The multi-line thing

This is the upstream issue. Bracket Pair Colorizer might have used some tricks (technically, we can fake multi-line decoration with multiple single-line decorations 😂). However, I am not a fan of this.

Decorations inside code blocks

Interesting. It is doable to disable decorations there. I can look into it this weekend.
