Bug: Paste + Enter causes text to disappear without sending

[madsonhsd-dev]

Description

When pasting text into the chat input and pressing Enter, the pasted text disappears instead of being sent. Typing normally (without pasting) works fine.

Steps to Reproduce

1. Copy any text
2. Paste it into the chat input
3. Press Enter immediately after pasting
4. The text vanishes

Root Cause

contenteditable div race condition: paste event and keydown (Enter) fire in parallel, DOM not updated yet when Enter checks for content, submit aborted.

Environment

-OpenCode 1.16.2 (npm: opencode-ai)
-Kubuntu Linux, KDE Konsole

Suggested Fix

-Read DOM directly on Enter instead of stale state
-Add isPasting flag
-Use requestAnimationFrame before content check

This issue might be a duplicate of existing issues. Please check:

• Paste-then-type text corruption in command line input box: content overwriting/loss #22785: Paste-then-type text corruption in command line input box — similar paste-related content loss in the input
• Text after paste content will be cut #21475: Text after paste content will be cut — similar symptom where content disappears after pasting

If your issue is distinct (specifically triggered by pressing Enter immediately after paste, rather than typing after paste), please add a note clarifying the difference so maintainers can track it separately.

This may be fixed in v1.18.4 by #37483, which changed paste handling to synchronously insert plain text and update prompt state. Could you test on v1.18.4 and confirm whether paste followed immediately by Enter now sends correctly?
