fix: prevent comment submission during IME composition

[717986230]

Summary

Prevents comments from being submitted while an IME composition is in progress.

Changes

• Checks e.nativeEvent.isComposing before submitting a new comment with Enter.
• Checks e.nativeEvent.isComposing before submitting an edited comment with Enter.
• Applies the guard to both wrapper onKeyDown handlers and LiteTextEditor onEnterKeyPress handlers.

Why

When typing Chinese or other IME-based text, pressing Enter can be used to confirm the current composition. Without checking isComposing, the comment can be submitted unexpectedly before the user finishes typing.

📝 Walkthrough

Walkthrough

Two comment submission components have been updated to prevent premature form submission when using IME (Input Method Editor) text composition. The changes add a !e.nativeEvent.isComposing check to the Enter-key handlers, blocking submission attempts triggered during Asian language input composition.

Poem

🐰 With whiskers twitching, I detect a fix so neat,
When typing Chinese characters, Enter won't retreat!
The IME knows when fingers dance mid-compose,
No premature submissions—just words, perfectly prose. ✨
