Crash reports started trickling in. Users would be working as normal in the app until, without warning, the browser locked up. Behind the scenes, an infinite React component tree was quietly growing in memory, and React 19’s <Activity> was keeping it alive long enough to hide the problem. The culprit? An AI coding agent and a deleted comment.
崩溃报告开始陆续出现。用户在应用中正常工作，直到没有警告地，浏览器锁死。在后台，一个无限的React组件树在内存中悄然增长，而React 19的 <Activity> 让它活得足够久以隐藏问题。罪魁祸首？一个AI编码代理和一个被删除的注释。
I’ve been building Outlyne, an AI-powered website builder, with my co-founder for the last year and a half. The primary UI is a Figma-like canvas with the pages of your website lined up horizontally:
在过去的一年半里，我和我的联合创始人一直在构建 Outlyne，一个 AI 驱动的网站构建器。主要的用户界面是一个类似 Figma 的画布，您的网站页面水平排列：
Each page has a header and footer, and each header and footer render an HTML popover that opens as a sidebar on the right so that users can choose between header and footer variants and decide what content to include:
每个页面都有一个头部和一个尾部，每个头部和尾部都会渲染一个 HTML 弹出窗口，该窗口作为右侧的侧边栏打开，以便用户可以选择头部和尾部变体并决定包含哪些内容：
The variants are rendered as scaled-down versions of the actual header and footer components, so the page’s header and footer each render a UI that itself renders more headers and footers with different props. That’s inherently recursive, which is fine as long as the recursion bottoms out. But if a preview ever renders the editor UI, which then renders previews again, the recursion never stops, and you end up in an infinite render loop.
变体被渲染为实际头部和脚部组件的缩小版本，因此页面的头部和脚部各自渲染一个UI，该UI本身又渲染更多具有不同属性的头部和脚部。这本质上是递归的，只要递归能够结束，这没问题。但如果预览渲染了编辑器UI，然后又渲染预览，递归就永远不会停止，最终你会陷入无限渲染循环。
Outlyne’s architecture made the solution straightforward. Webpage components only include the conten...
