Windows Terminal version

1.22.2362.0

Windows build number

10.0.19045.4651

Other Software

No response

Steps to reproduce

  1. Open a cmd shell in Windows Terminal.
  2. Type Ctrl+A
  3. Move the cursor left so it's before the ^A.
  4. Type a bunch of characters so the ^A is pushed past the end of the line.

Expected Behavior

The ^A should eventually wrap over onto the next line.

Actual Behavior

Once the ^A reaches the rightmost column, the line editor stops responding to any further keystrokes. In the debugger I can see it's stuck in an infinite loop here:
