Continuous Scrolling Bug in Claude VS Code Extension Conversation View

Bug Description
I'm encountering a strange issue while using Claude Code in VS Code. Whenever the conversation is close to reaching the automatic compression threshold, the interface starts scrolling the conversation feed upwards continuously and uncontrollably.

I recorded a video to demonstrate the behavior. Please let me know if you'd like me to share it or if there’s any additional information I can provide to help debug this.
