What's Wrong?

When I type CJK character in the terminal(powershell), with windows11's microsoft default Input Method, it apperar at the position of cursor.

However, when in claude, it appear in a far away from the cursor's position. Pls see the vedio below:

What Should Happen?

The Input method's panel should appeared near the cursor, as the powershell behaves.
