ai-chatbot Discrepancy in Message Rendering Order During Streaming with New AI SDK Features

I've observed that with the latest AI SDK features implemented in chat/route.ts, the rendering order of messages during streaming does not match the final rendered output after a page refresh. Specifically, during streaming:

Streaming Behavior: Only one aggregated message is displayed. As additional text is streamed, it pushes the tool component forward (i.e., the tool invocation appears to shift its position relative to the streamed text).
Post-Refresh Behavior: After refreshing the page, the message is split into two separate messages with the tool component rendered first, as expected.

I have temporarily reverted to version 'ai': '4.0.11', until the issue is resolved.

t seems that messages are being merged somewhere in the frontend. In route.ts, the saved messages contain 2 or 3 items, but on the frontend, they are reduced to just one.
