Because the agent cannot observe the contents or state of the spawned pop-up, it fails to complete workflows that require interacting with pop-ups. Steps to Reproduce: 1. Launch an agent session in VS Code that interacts with the integrated browser. 2. Navigate to any page or run a task that triggers a pop-up window or modal (e.g., third-party OAuth authentication, `window.open()`, or JavaScript alert/prompt). 3. Observe that the pop-up opens visually in the integrated browser UI. 4. Check the agent's context/tool calls: the agent does not receive the new window's URL, DOM snapshot, or state and remains blocked or unaware of the pop-up. ### Expected Behavior Spawned pop-up windows and modal dialogs from the integrated browser should automatically pipe their state/DOM context back to the agent session so it can continue execution. ### Actual Behavior The pop-up context remains detached, leaving the agent blind to the new window and unable to proceed. ”
