Escape key to interrupt response not working in some sessions

[Latigid-Sam]

Description

The Escape key to interrupt Claude's response does not work consistently across sessions. The UI shows "Esc to interrupt" during the thinking/response phase, but pressing Escape has no effect in some sessions while working correctly in others.

Steps to Reproduce

1. Start a Claude Code session
2. Ask Claude a question that triggers a lengthy response
3. While Claude is responding (thinking indicator shows "Esc to interrupt"), press Escape
4. Expected: Response stops immediately
5. Actual: In some sessions, nothing happens - Escape is ignored

Environment

• Platform: macOS (Darwin 25.1.0)
• The issue appears session-specific - Escape works in some threads but not others within the same terminal

Workaround

Using Ctrl+C successfully interrupts the response, but this is inconsistent with the UI hint showing "Esc to interrupt".

Additional Context

User reported that double-Escape (for rewind) also did not trigger, suggesting Escape key events may not be reaching Claude Code in affected sessions.
