Although, when I open up a new chat the chat displays that it has defaulted to 1M context, when I display the actual context it doesn't show the 1M context.

I have to mnaully toggle it everytime.

从 /chat 入口开始，通过打开一个新聊天并检查其显示的上下文设置，复现应用版本 0.2.33 中报告的行为。追踪聊天报告 1M 上下文但实际上下文不同的原因，然后验证新聊天无需手动切换即可使用 1M。
