Original Pull Request: https://github.com/microsoft/terminal/pull/16445

State: closed
Merged: Yes

This prevents an issue in conhost where older versions of Windows Terminal (including the ones currently inbox in Windows, as well as stable and preview) will still cause WSL interop to hang on startup.

Since VT input is erroneously re-encoded as Win32 input events on those versions, we need to make sure we request the cursor position before enabling Win32 input mode. That way, the CPR we get back is properly encoded.
