有没有办法立即显示最新的回复？目前，我使用这段代码：

````plaintext
  api.onPageChange(() => {
    if (window.location.pathname === "/") {
      const container = document.querySelector(".latest-topic-list");
      if (!container || container.dataset.modified === "true") return;

      fetch("/posts.json?order=created")
        .then(res => res.json())
        .then(data => {
          const replies = data.latest_posts
            .filter(p => p.post_number > 1 && !p.topic_slug.includes("private-message"))
            .slice(0, 15);

          const topicFetches = replies.map(post =>
            fetch(`/t/${post.topic_id}.json`)
              .then(res => res.json())
              .then(topic => {
                return {
                  post,
                  category: topic.category_id ? topic.category_name : null,
                  tags: topic.tags || []
                };
              })
          );

          Promise.all(topicFetches).then(results => {
            const rows = results.map(({ post, category, tags }) => {
              const url = `/t/${post.topic_slug}/${post.topic_id}/${post.post_number}`;
              const avatarUrl = post.avatar_template.replace("{size}", "45");
              const excerpt = post.excerpt?.replace(/<\/?[^\s>]+(\>|$)/g, "")?.slice(0, 120) + (post.excerpt?.length > 120 ? '...' : '') || '';

              const categoryHtml = category
                ? `<span style="font-size: 0.85em; color: #666;">Categoria: <strong>${category}</strong></span><br>`
                : '';

              const tagsHtml = tags.length
                ? `<span style="font-size: 0.85em; color: #666;">Tags: ${tags.map(tag => `<span style="background:#eee; padding:2px 6px; border-radius:3px; margin-right:4px;">${tag}</span>`).join("")}</span>`
                : '';

              return `
                <tr class="topic-list-item">
                  <td class="main-link clearfix">
                    <div style="display: flex; align-items: center; gap: 16px; padding: 8px 0;">
                      <div style="flex-shrink: 0;">
                        <a class="avatar-link" href="/u/${post.username}">
                          <img loading="lazy" width="45" height="45" src="${avatarUrl}" class="avatar" alt="${post.username}">
                        </a>
                      </div>
                      <div style="display: flex; flex-direction: column; justify-content: center; padding-top: 8px; padding-bottom: 8px;">
                        <span class="link-top-line" style="margin-bottom: 6px;">
                          <a href="${url}" class="title raw-link">${excerpt}</a>
                        </span>
                        <div class="link-bottom-line">
                          ${categoryHtml}
                          ${tagsHtml}
                        </div>
                      </div>
                    </div>
                  </td>
                </tr>
              `;
            }).join("");

            // Cria o container da seção de últimos comentários
            const latestRepliesContainer = document.createElement("div");
            latestRepliesContainer.className = "latest-replies-container";
            latestRepliesContainer.style.marginTop = "2em";

            latestRepliesContainer.innerHTML = `
              <table class="topic-list latest-topic-list">
                <thead>
                  <tr>
                    <th class="default">Últimos Comentários</th>
                  </tr>
                </thead>
                <tbody>
                  ${rows}
                </tbody>
              </table>
            `;

            container.parentNode.insertBefore(latestRepliesContainer, container.nextSibling);
            container.dataset.modified = "true";
          });
        })
        .catch(error => {
          console.error("Erro ao buscar últimos comentários:", error);
        });
    }
  });
/script```

但内容平均需要 2 秒钟才会出现。带有“最新评论”的右侧边栏块也是如此。这正常吗？
