When using the new "expand" feature on a PR created from a session, the expanded PR view is not linked to the existing session (it only shows a "new session" button in the header). Additionally, the button for marking a draft PR ready for review is disabled in the sidebar, but in the session PR view it is enabled.

从桌面应用中的 /chat 开始，使用由 session 创建的 draft PR 重现该报告，然后使用新的展开功能。比较展开后的 PR 视图与 session PR 视图，包括 session 链接和 ready-for-review 控件。完成的标准是，展开后的视图仍与现有 session 保持链接，并且 draft 状态控件的行为保持一致。
