Single leading space is not displayed

Consider this program

void Main()
{
    Console.WriteLine("a");
    Console.WriteLine(" a");
    Console.WriteLine("  a");
}

The expected output is

a
 a
  a

But LINQPad displays the output as

a
a
  a

If you copy-paste the output into another program, the leading space is there as expected. (LINQPad version 4.55.03.)
