会话页能否支持托拽成单独的一个窗口？

当同一个服务器的会话在分别在两个不同的显示器上显示的时候，就必须重新打开应用程才行，能不能增加会话页可以托拽成单独的窗口？

The issue names no files, tests, or entry points. Begin by locating the session-page and window-management implementation, then clarify how a session should detach and behave across displays. Done should include a defined drag-to-separate interaction and verification that sessions from the same server can appear in independent windows.
