[hirsaeki]

Windows Terminal version

1.24.251216004

Windows build number

26200.7462

Other Software

CorvusSKK: 3.3.1

Steps to reproduce

1. Install Windows Terminal Preview 1.24.251216004-preview.
2. Ensure CorvusSKK 3.3.1 is installed and set as the current IME.
3. Launch Windows Terminal Preview (non-elevated; not running as Administrator).
4. Open a tab (e.g., PowerShell).
5. Switch to Japanese input with CorvusSKK.
6. Type a reading (e.g., nihongo).
7. Trigger conversion / candidate selection (e.g., Space / usual CorvusSKK conversion action).

Expected Behavior

Candidate window / composition UI should be visible near the caret position, allowing normal candidate selection.

Actual Behavior

Candidate window / composition UI is not visible.
However, conversion still happens internally (confirming commits some candidate), so selection becomes “blind”.
