mermaid can't render on preview

[yasumichi]

I try fix.

(function () {
    console.log("gme.js loaded.");

    var renderKatex = function() {
        var mathElems = document.getElementsByClassName("katex");
        var elems = [];
        for (const i in mathElems) {
            if (mathElems.hasOwnProperty(i)) elems.push(mathElems[i]);
        }

        elems.forEach(elem => {
            katex.render(elem.textContent, elem, { throwOnError: false, displayMode: elem.nodeName !== 'SPAN', });
        });
    };

    var renderMermaid = function() {
        document.querySelectorAll('.mermaid').forEach(async (node, index) => {
            const graphDefinition = node.textContent;
            const graphId = `mermaid-${index}`;
            node.id = graphId;
            const renderResult = await mermaid.mermaidAPI.render(graphId, graphDefinition, node);
            node.innerHTML = renderResult;
        });
    };

    var renderAll = function() {
        renderKatex();
        renderMermaid();
    };

    document.addEventListener("DOMContentLoaded", function(){
        var preview = document.querySelector("#preview");
        if (preview) {
            const config = { attributes: false, childList: true, subtree: false };

            const observer = new MutationObserver((mutations) => {
                mutations.forEach((mutation) => {
                    if (mutation.addedNodes.length == 1) {
                        observer.disconnect();
                        renderAll();
                        observer.observe(preview, config);
                    }
                });
            });

            observer.observe(preview, config);
        }
        renderKatex();
    });
})();

It will be drawn up to halfway.
But error "syntax error in text mermaid" occurs.

use mermaid.run() instead of mermaid.render().
