⚠️ Bug Report: Duplicate task created with last character(s) of input#4369

When adding a new task, an additional task is automatically created containing only the last character(s) of the typed title.

Steps to reproduce:
Tap “Add task”
Type a task name (e.g. “AI 도구 목록”)
Confirm/submit

Expected: One task created — “AI 도구 목록”
Actual: Two tasks created — “AI 도구 목록” and “록”
This issue appears to occur specifically when typing in Korean on the web app. The mobile app does not reproduce this issue. Korean text input uses IME (Input Method Editor) for character composition, and the duplicated fragment seems to result from the final composed character being submitted twice — once as part of the full title, and once as a standalone entry. This may be caused by improper handling of the compositionend event in the web frontend.

As a paid user, I expected basic Korean input to work reliably, especially given that Korean is listed as a supported language. I hope this gets prioritized accordingly.
