Korean IME input issue: First character incorrectly rendered as English letter #434
Description
Hello, I'm a developer based in South Korea currently using react-spreadsheet. First of all, thank you for creating and maintaining such a great tool.
I’ve encountered an issue when entering Korean text into a cell. While English input works perfectly, Korean input seems to have a problem related to IME (Input Method Editor). Specifically, when typing in Korean using a Korean keyboard, the first character is incorrectly rendered as a lowercase English letter. For example, when I try to type "안녕" (which means "hello"), it appears as "dㅏㄴ녕".
Interestingly, this issue only occurs when I single-click a cell to activate it and start typing. If I double-click the cell (so that the cursor is visible and the cell is in edit mode), Korean input works correctly without any issues.
It would be greatly appreciated if you could look into this issue. Please let me know if you need any additional information to help reproduce the problem.
Thank you again for your hard work!
