SHIFT+END on Linux WSL generates an escape sequence

[xoofx]

When pressing SHIFT+END with the following program:

using System;

namespace TestConsole
{
    class Program
    {
        static void Main(string[] args)
        {
            // Console.TreatControlCAsInput = true;
            while (true)
            {
                var key = Console.ReadKey(true);
                Console.WriteLine($"Key: {key.Key} Modifiers: {key.Modifiers} Char: {(key.KeyChar < ' ' || (int)key.KeyChar >= 126 ? "0x" + ((int)key.KeyChar).ToString("x2") : key.KeyChar.ToString())}");
                if (key.Key == ConsoleKey.C && (key.Modifiers & ConsoleModifiers.Control) != 0)
                {
                    break;
                }
            }
        }
    }
}

It generates the following sequence on Linux:

Key: Escape Modifiers: 0 Char: 0x1b
Key: D1 Modifiers: 0 Char: 1
Key: 0 Modifiers: 0 Char: ;
Key: D2 Modifiers: 0 Char: 2
Key: F Modifiers: Shift Char: F

instead of generating the following on Windows:

Key: End Modifiers: Shift Char: 0x00

In kalk, it's breaking the start selection + move cursor to end, while SHIFT+HOME is working just fine.

So it's either a bug in .NET or in WSL. I haven't checked this in a VM/real Linux so see how it behaves...
