Windows Terminal version

1.21.1272.0

Windows build number

10.0.19045.4291

Other Software

QEMU 9.0

Steps to reproduce

Run QEMU with unix-like guest OS which serial port connected to console (WindowsTerminal). Resize Terminal window.

Expected Behavior

As I understand WindowTerminal must emit control sequence to notify of width/height change.
Here is a screenshot of similiar system in another terminal that resize correctly:

Actual Behavior

Window is reisized but internal structure get corrupt. Notice the cursor moved outside it normal position. I think this is a result of adapation maked by WindowsTerminal itself.

But most unix terminal programs can handle terminal resize notification. It will be very nice to have it for seamless integration.
