[BUG] /feedback text area rejects input — "Please describe the issue before submitting." loops even after typing

Summary

Running /feedback in the terminal opens the "Submit feedback / bug report" form
("Describe the issue below:"), but pressing Enter after typing text always
results in "Please describe the issue before submitting." — the form never
accepts the input and the report cannot be submitted.

Environment

• Claude Code CLI: 2.1.241

Steps to reproduce

1. Run /feedback
2. Type any text into the "Describe the issue" field
3. Press Enter
4. Observe: "Please describe the issue before submitting." (loops, cannot proceed)

Expected behavior

The typed description should be accepted and the feedback/bug report submitted.

Actual behavior

The form rejects submission regardless of typed content, effectively making
/feedback unusable for reporting bugs (including this one).
