Environment data

PS Version: 7.2.1
PS HostName: ConsoleHost
PSReadLine Version: 2.1.0
PSReadLine EditMode: Windows
OS: Linux Porre-Ubuntu 4.4.0-19041-Microsoft #1237-Microsoft Sat Sep 11 14:32:00 PST 2021 x86_64 x86_64 x86_64 GNU/Linux

Steps to reproduce

1. Open a Windows Subsystem for Linux window. I was able to produce this in the standard console window ("debian.exe" and "ubuntu.exe") and Windows Terminal ("WindowsTerminal.exe" and a GNU/Linux profile)
2. Install PowerShell via the instructions in https://docs.microsoft.com/en-us/powershell/scripting/install/installing-powershell-on-linux?view=powershell-7.2
3. Open PowerShell via "pwsh"
4. Press and hold the Right Shift key
5. Press the End key

I did verify that the key combination is bound via the following:

$ Get-PSReadLineKeyHandler -Chord 'Shift+End'

Selection functions
===================

Key       Function   Description
---       --------   -----------
Shift+End SelectLine Adjust the current selection to include from the cursor to the end of the line

Just in case this helps, here are the results of "showkey -a" for WSL Ubuntu for my End, Shift+End, CTRL+End, and ALT+End:

$ showkey -a

Press any keys - Ctrl-D will terminate this program

         70 0106 0x46

Expected behavior

The key combination should select from the currently focused cursor position to the end of the line.

Please note that the Shift+Home key combination seems to work correctly.

Actual behavior

Pressing the shift key and the end key inserts ";2F" in a console window and "^[1;2F" in Windows Terminal.

Console.ReadKey returns unexpected ConsoleKeyInfo when pressing Shift+End in WSL. Opened the issue in .NET repository: dotnet/runtime#63644.
