Description
This is with PowerShell 7.3.0-preview.7, which runs on top of .NET 7-preview.7.
Running [System.Console]::ReadKey() in PowerShell, and then press UpArrow, it returns the escape sequences character by character -- Escape and then A.
It's the same to other arrow keys: DownArrow, LeftArrow, RightArrow
However, when using Console.ReadKey in an EXE built against .NET 7-preview.7, it returns UpArrow (and other arraow keys) as expected. Any ideas about what may cause this difference?

Reproduction Steps
- Run PowerShell 7.3.0-preview.3, which runs on top of .NET 7-preview.7.
- Run
[System.Console]::ReadKey() - Press UpArrow
Expected behavior
[System.Console]::ReadKey() returns a ConsoleKeyInfo with those values: KeyChar: 0, Key: UpArrow, Modifier: 0
Actual behavior
[System.Console]::ReadKey() returns a ConsoleKeyInfo with the Escape key, and then a second ReadKey returns A
However, when using Console.ReadKey from an EXE that's built against .NET 7-preview.7, it works as expected:
Regression?
Not as far as I know. I observe the same behavior in .NET 6.
