Vscode-markdown: syntax.decorations: The phase of recognizing <code> tag is broken

[yumetodo]

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

Thank you for the report. Looks a bit hard to handle...

[yzhang-gh]

It should be fixed in the dev build.

[yumetodo]

@yzhang-gh I install build 1.0.29, then, work fine!

BTW, Another pattern cause bug found...

`a
a`

This should be recognize like <code>a a</code>.

You are right. However vscode decorations cannot cover multi-lines. So this is the best we can do now.

vscode decorations cannot cover multi-lines.

I'm not sure about vscode decorations. However, as far as I see, Bracket Pair Colorizer do it (bracketPairColorizer.showVerticalScopeLine, I don't know Bracket Pair Colorizer really use vscode decorations system to draw)

How do you think about code tag syntax in code block syntax?

```
aaa
`a`
a
`````
    ```a```

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.

[yzhang-gh]

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.

Thank you for your fix!
