- feat(git-log): **A rebuilt Commit history tab.** Virtualized and paged for long histories, with branch and author filters, a pushed/not-pushed marker on every commit, and your filter choices remembered per folder. - feat(sidebar): **Group sessions by git worktree.** Turn on "Show worktree folders" to nest each worktree under its repo as a collapsible, branch-labelled sub-group. On by default now, alongside "Show completed." - feat(delegation): **Mention an agent with `@` to hand it the work.** Naming a sub-agent in your message now delegates that work straight to it — one delegation per agent named. - feat(chat): **View a diff from a reply's changed files.** Each modified file now has a View Diff button that opens its diff in an editor tab, on web and desktop. - feat(layout): **Session stats on mobile.** The mobile status bar now shows your session stats on the left. - fix(chat): **No more phantom tool cards after a turn ends.** Empty tool calls left by interrupted or retried turns no longer resurface and inflate the tool-group and poll cards. - fix(messages): **The focus ring follows your keyboard, not your mouse.** Clicking a message no longer leaves a focus outline; keyboard navigation still shows one. Thanks to @youxikexue (#338). - fix(chat): **A tidier connection indicator.** It now aligns with the send button and uses a muted colour when connected instead of a green heart. - fix(layout): **No stray scrollbar on the branch selector.** The popup now sizes to its rows, so filtered lists have no leftover scrollbar or empty space. - chore(acp): **Refreshed the bundled agent versions.** Claude Code 0.61.0, Gemini 0.52.0, CodeBuddy 2.126.0, Kimi Code 0.29.0, Grok 0.2.111, and Cursor 2026.07.20. ----------------------------- # 发布版本 0.21.6 - 功能(提交历史)：**重建的「提交」标签。** 虚拟化分页加载，长历史也流畅，支持按分支与作者筛选，每条提交显示是否已推送，筛选选择按文件夹分别记住。 - 功能(侧边栏)：**按 git 工作树分组会话。** 打开「显示工作树文件夹」，即可把每个工作树作为可折叠、以分支命名的子分组归到所属仓库下。现与「显示已完成」一并默认开启。 - 功能(委派)：**用 `@` 提及某个智能体，即可把工作交给它。** 在消息中点名子智能体，现在会直接把这部分工作委派给它——点名几个就生成几个委派。 - 功能(聊天)：**在回复的变更文件上查看 diff。** 每个被修改的文件现在都带「查看 Diff」按钮，点击即在编辑器标签中打开其 diff，网页端与桌面端均可用。 - 功能(布局)：**移动端显示会话统计。** 移动端状态栏现在在左侧显示你的会话统计。 - 修复(聊天)：**回合结束后不再残留幽灵工具卡片。** 中断或重试回合留下的空工具调用，不再重新出现并撑大工具分组与轮询卡片。 - 修复(消息)：**焦点框跟随键盘，而非鼠标。** 点击消息不再留下焦点轮廓，键盘导航时仍会显示。感谢 @youxikexue 的贡献（#338）。 - 修复(聊天)：**更整洁的连接指示。** 现在与发送按钮对齐，「已连接」时改用柔和色而非绿色心形。 - 修复(布局)：**分支选择器不再出现多余滚动条。** 弹层现在按其行高自适应，筛选后的列表既无残留滚动条也没有空白。 - 维护(智能体)：**刷新内置的智能体版本。** Claude Code 0.61.0、Gemini 0.52.0、CodeBuddy 2.126.0、Kimi Code 0.29.0、Grok 0.2.111，以及 Cursor 2026.07.20。

问题
在 Windows 桌面版或通过分享链接打开的网页端中，Agent 输出内容后，点击消息文本或正文空白处，整个消息滚动区域会出现焦点边框，边框包含右侧滚动条；点击区域外后消失。
复现步骤：
预期行为：鼠标点击正文后不显示键盘焦点提示，但仍可使用方向键、PageUp/PageDown 等按键滚动消息。通过 Tab 键进入消息区域时，应继续显示焦点提示。
原因
VirtualizedMessageThread为支持键盘滚动，给消息滚动视口设置了tabIndex=0，并在点击非交互正文时调用focus()；视口同时使用focus-visible:ring-2提供键盘焦点提示。Chromium/WebView 会将鼠标事件中调用的程序化
focus()判定为:focus-visible，因此鼠标点击也触发了原本用于键盘导航的焦点环。相关行为由提交259989f引入。方案选择
考虑过以下方式：
tabIndex或点击聚焦：会破坏现有键盘滚动；本 PR 采用方案 3，保留原有键盘操作和无障碍设计，只修正不同输入方式下的视觉反馈。
改动
focus()前，为消息视口写入临时的鼠标焦点来源标记；:focus-visible时，通过局部样式隐藏焦点环；tabIndex、点击聚焦、交互元素过滤、右键处理和键盘焦点样式。改动仅涉及
VirtualizedMessageThread及对应回归测试，不修改全局 ScrollArea 或基础焦点样式。影响评估
验证
git diff --check均通过；
