Steps to reproduce

Note:

• The symptom is reminiscent of the problem described in Select-String doesn't render VT (ANSI) escape sequences in its for-display output with input from external programs on Windows #18294, which was inappropriately closed.
• However, unlike the latter, the symptom described here also affects running in Windows Terminal, not just conhost.exe console windows.
• As in the latter issue, this is merely a display problem: it doesn't affect capturing or redirecting the output.
• Write-Output is used below for simplicity; a real-world use case would be Tee-Object -Variable out, where you want both to-display output and to capture the (unconditionally colored) output in a variable.

# From WSL (using a WSL-installed PowerShell version)

# Dummy command that is seemingly necessary to provoke the symptom *right away*.
# Without it, the code below must be run *twice* to surface the symptom.
/bin/echo | Write-Output 

# !!  Broken display output
script -qc 'ls --color=auto /mnt/c/windows' /dev/null | Write-Output

'----------------'

# OK, due to (...) enclosure
(script -qc 'ls --color=auto /mnt/c/windows' /dev/null) | Write-Output

Expected behavior

Both script commands should properly relay the colored, columnnar ls output.

Actual behavior

The first script command's layout is broken.
