To be more specific it works if I don't scroll at all. If I scroll up and then down to bottom of the page then it doesn't scroll automatically.

@ngxson This is still an issue and appears quickly with regular usage. In addition to what is described above, once the assistant response is finished generating, the UI jumps back up to the user's message. So, maybe there is an issue with scrollToBottom or how it is invoked.

[ngxson]

Yes it could be. The scrollToBottom is kinda low-effort implementation and would be nice if someone can re-engineering it.

The problem is that there is a logic to detect if you're scroll to near-bottom or not, and the auto scroll only get activated if you're near the bottom of the page. However, it seems to be inaccurate with different screen sizes.
