Win32 OpenSSH eats up encoding for any sixel images

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest version
• Search the existing issues.

Steps to reproduce

My current pipeline is Windows Terminal -> pwsh.exe -> ssh.exe -> WEB -> sshd.exe -> pwsh.exe -> type C:\snake.six

When I print out snake.six which is a text file with a sixel-encoded image I get nothing.

Expected behavior

PS> type C:\snake.six
[should display image]
PS>

Actual behavior

PS> type C:\snake.six

Visuals

Reproduce the reported Windows Terminal -> pwsh.exe -> ssh.exe -> sshd.exe -> pwsh.exe pipeline with C:\snake.six, then trace where the sixel-encoded text is lost. Done means the same command preserves the image data and displays the sixel image through Win32 OpenSSH.
