Environment

Windows build number: 10.0.18362.0
Windows Terminal version: 1.2.2381.0
ssh-keygen 7.7.2.1 

Steps to reproduce

1. Open a new powershell shell in Windows Terminal
2. run the ssh-keygen powershell command.

Expected behavior

When prompted to specify the file to save the key in, I am able to enter text.

Actual behavior

Typing does not produce visible text, and hitting enter does not cause ssh-keygen to continue. I am able to break execution with Control-z, however.

Notes

ssh-keygen behaves as expected when run in a powershell shell in conhost.exe.
