研究方向

首先，使用 htm.bind(h) 執行提供的 JavaScript 重現程式碼，並將其虛擬 DOM 輸出與預期的 JSON 進行比較。追蹤 tagged template 如何解析未閉合的 meta 和 link 元素；當這些元素仍保持自閉合，且 head 的子元素保留所示結構而沒有未回報的解析錯誤時，即表示完成。

描述

discussion question

An exception occurred when parsing an unclosed label using htm, but no error was reported.

This leads to the wrong virtual dom object.

An exception occurred when parsing an unclosed label with "htm", but no error was reported.

This resulted in the wrong "virtual dom" object.

(async () => {
    function h(type, props, ...children) {
        return {
            type,
            props,
            children
        };
    }
    const {default: htm} = await import('https://unpkg.com/htm?module');
    const html = htm.bind(h);
    return html;
})().then(html => {
    return html`
