GitHub Copilot Chat - Output cuts off #279291
Description
Type: Bug
Sometimes the output of the agent just stops and cuts off. The agent starts with a sentence and then the message suddenly ends.
I'm not able to reproduce it in a reliable way. The issue is also model unrelated. It does not matter which model you select.
What I found out is that the cutoff always happens after a code block.
