[BUG] Response auto-interrupts after Bash tool completion, stays stuck in "Interrupted" state

What's Wrong?

Claude Code intermittently enters an "Interrupted" status on its own after a Bash tool call completes successfully. The user does not press Escape or Ctrl+C.
The tool output is displayed correctly, but the response never continues — it just shows "Interrupted · What should Claude do instead?"

Typing a follow-up message also gets stuck in the same "Interrupted" state. The only way to recover is to exit the session and resume.

Expected behavior: Response should continue generating after the tool call returns output.

Actual behavior: Response enters "Interrupted" state automatically. Follow-up messages also get stuck. Must exit and resume session to recover.

Environment:

• OS: Linux (Ubuntu, kernel 6.8.0-90-generic)
• Shell: bash
• Claude Code model: Opus
• The Bash commands involved are SSH sessions to remote servers, often running Python heredocs over SSH

Notes:

• Happens intermittently, not every time
• Tool output is fully received and displayed before the interruption
• May be related to long-running or multi-line Bash tool calls over SSH
• No user keypress triggers the interrupt

What Should Happen?

The session should continue as normal.

Steps to Reproduce

Steps to reproduce:

1. Run a Bash tool call with an SSH command (e.g., ssh user@host "python3 << 'EOF' ... EOF")
2. Wait for the command to complete (output is returned successfully)
3. Response stream stops and shows "Interrupted" status without user input
