Environment

• OS: Ubuntu Linux
• Browser: Firefox / Chrome
• IME: fcitx5
• OpenClaude version: v0.9.2
• Provider: Google Gemini

Bug Description

Japanese IME input does not work in the Web Dashboard chat input field.
Characters cannot be entered at all when using Japanese input (fcitx5).
English input works fine.

Root Cause

In dashboard/index.html line 847, the Enter key handler does not check
e.isComposing, causing IME composition events to conflict with the send action.

Before (buggy):

if (e.key === 'Enter' && !e.shiftKey) { e.preventDefault(); sendMessage(); }

After (fixed):

if (e.key === 'Enter' && !e.shiftKey && !e.isComposing) { e.preventDefault(); sendMessage(); }

Additional Notes

• Firefox does not work even after the fix; Chrome works correctly after the fix
• Browser cache must be cleared after applying the fix

Workaround

Apply the fix above to dashboard/index.html and use Chrome browser.

Additional Note - Firefox

After applying the !e.isComposing fix, Chrome works correctly.
However, Firefox still does not accept Japanese IME input.

Firefox may require separate handling of the compositionend event, for example:

let isComposing = false;
chatInput.addEventListener('compositionstart', () => isComposing = true);
chatInput.addEventListener('compositionend', () => isComposing = false);

And then check the isComposing flag in the keydown handler instead of e.isComposing.

This would make the dashboard work correctly on both Chrome and Firefox for CJK input.
