我的语法强调语法注入有什么问题？

Question

我正在关注this example以便在markdown中进行简单的语法注入。

{
    "fileTypes": [],
    "injectionSelector": "L:markup.fenced_code.block.markdown",
    "patterns": [
        {
            "include": "#superjs-code-block"
        }
    ],
    "repository": {
        "superjs-code-block": {
            "begin": "superjs",
            "end": "(^|\\G)(?=\\s*[`~]{3,}\\s*$)",
            "contentName": "meta.embedded.block.superjs",
            "patterns": [
                {
                    "include": "source.js"
                }
            ]
        }
    },
    "scopeName": "markdown.superjs.codeblock"
}

上面的代码存在一个小问题 - 只要在受防护的代码块中出现字符串superjs，剩下的就会被渲染为superjs，这会破坏fenced代码块语法突出显示其他嵌入式语言。

{
   "foo": "superjs"
}

我想通过关注markdown.tmLanguage.json来修复它。

{
    "fileTypes": [],
    "injectionSelector": "text.html.markdown",
    "patterns": [
        {
            "include": "#fenced_code_block_superjs"
        }
    ],
    "repository": {
        "fenced_code_block_superjs": {
            "begin": "(^|\\G)(\\s*)(`{3,}|~{3,})\\s*(?i:(superjs)(\\s+[^`~]*)?$)", 
            "beginCaptures": {
                "3": {
                    "name": "punctuation.definition.markdown"
                }, 
                "5": {
                    "name": "fenced_code.block.language"
                }, 
                "6": {
                    "name": "fenced_code.block.language.attributes"
                }
            }, 
            "end": "(^|\\G)(\\2|\\s{0,3})(\\3)\\s*$", 
            "endCaptures": {
                "3": {
                    "name": "punctuation.definition.markdown"
                }
            }, 
            "name": "markup.fenced_code.block.markdown", 
            "patterns": [
                {
                    "begin": "(^|\\G)(\\s*)(.*)", 
                    "contentName": "meta.embedded.block.superjs", 
                    "patterns": [
                        {
                            "include": "source.js"
                        }
                    ], 
                    "while": "(^|\\G)(?!\\s*([`~]{3,})\\s*$)"
                }
            ]
        }
    },
    "scopeName": "markdown.superjs.codeblock"
}

然而它不起作用，我也不知道如何调试它。
