IME Composition Input Rendering Lag for Non-Latin Scripts.

Bug Description
The current version of Claude Code has an issue where IME-based input (such as Korean), which relies on composing characters, is not reflected smoothly in the input field as you type. Instead, characters only appear once the composition is complete, making the typing experience awkward. A similar issue occurs with Japanese input. See: https://github.com/anthropics/claude-code/issues/1547
Please improve the code so that Korean text input behaves naturally during composition.
