KaTeX不呈现HTML扩展命令,尽管有“strict:false”和“trust:true”选项

我正在尝试将LaTeX表达式嵌入到我的库的web文档中。

这是HTML代码 cargo ,Rust的构建系统,在HTML文档的头部放置文档:

<script>
    document.addEventListener("DOMContentLoaded", function() {
        renderMathInElement(document.body, {
            strict: false,
            trust: true,
            delimiters: [
                {left: "$$", right: "$$", display: true},
                {left: "\\(", right: "\\)", display: false},
                {left: "$", right: "$", display: false},
                {left: "\\[", right: "\\]", display: true}
            ]
        });
    });
</script>

这个 .tex 正在嵌入的:

\begin{cases}
    \operatorname{try\_get\_len\_of\_closed\_int\_intvl\_from\_0}: \href{Self}{google.com} \rightharpoonup usize \\
    \operatorname{try\_get\_len\_of\_closed\_int\_intvl\_from\_0} = i \mapsto \lvert [0..i] \rvert
\end{cases}

输出:

如何使KaTeX正确显示tex?
