Chat UI: chat view doesn't auto-scroll when an existing content part becomes larger #270
Description
Feature Description:
Currently, auto-scroll is only updated when receiving tokens from the (top-level) LLM. With eclipse-theia#15736, we introduced "Agent delegation", which can also render some content in the Chat View, without involving new tokens from the main Agent. This currently breaks auto-scroll.
There may also be similar cases, where a Chat ContentPart grows independently of new tokens (e.g. Command interaction, ...). Auto-scroll should handle these cases, if possible.
Expected result:
- when delegating a prompt to another Agent via the delegation tool, and if the users expands the details/summary group, auto-scroll should handle the delegated tokens and scroll as necessary
- bonus: auto-scroll should handle any kind of growing/shrinking content parts, even when new tokens aren't received in the Chat
