[Bug] Infinite UI re-rendering loop in /feedback dialog on Windows

Bug Description
● Title: Infinite UI re-rendering loop in /feedback dialog on Windows

Description:
When /feedback dialog opens, the terminal enters an infinite re-rendering loop - duplicating entire console history until buffer overflows, clears, and
restarts the loop.

Steps to reproduce:

1. Run /feedback with multiline text on Windows
2. Console starts duplicating content infinitely

Possible cause: Insufficient vertical space triggers repeated redraws.

Environment:

• Claude Code: v2.0.60

• Platform: win32
• Terminal: visualstudio
• Version: 2.0.60
