XYplorer Beta Club

XYplorer: 28.30.1900 (64-bit)
Windows: Microsoft Windows 11 Pro, build 26200
Display scaling: 100%
IME: Microsoft Korean IME

Location:
Tools > Customize File Associations

Type : '한글'
- Result : 'ㅎ하한한mf'
- Result : '한글'

Steps to reproduce:
1. Open Tools > Customize File Associations.
2. Select an item.
3. Edit it using the single-line inline editor.
4. Type the Korean word: 한글

Observed output:

- v28.30.1600, with both the current and legacy Microsoft Korean IME:
ㅎ하한한ㄱ그글글

- v28.30.1900, with the current Microsoft Korean IME:
ㅎ하한한mf

The composition bug is reproducible in both versions.
However, the exact malformed output changed after updating to
v28.30.1900. I have not determined whether this difference is
directly version-related.

Expected result:
한글

Additional findings:
- Reproducibility: 100%
- Enable surround selection = Off
- Editor Mode (F6) works normally
- Pasting completed Korean text works normally
- English direct input works normally
- Other XYplorer input fields tested so far work normally
- Reproduced with "Use previous version of Microsoft IME" both enabled and disabled
- Reproduced in a fresh instance: Yes
- The screen recording uses the Windows built-in Korean on-screen keyboard for visibility. The same IME composition-duplication behavior also occurs with a physical keyboard.

The ZIP archive contains a single MP4 screen recording only. It contains no executable files.

Is List Management's single-line editor the only place where it does not work correctly?
