Extract method over-indents second line of expression

Version Used: 15.3 Preview 7

:link: Originally revealed by ExtractMethodTests.TestUseExpressionWhenOnSingleLine_AndNotIsOnSingleLine in #21439.

Steps to Reproduce:

1. Use the following code

   using System;
   
   namespace ConsoleApp5
   {
       class Program
       {
           static void Main(string[] args)
           {
               bool b = true;
               Console.WriteLine(b !=
                   true ? b = true : b = false);
           }
       }
   }
   

2. Select b != true

3. Apply the Extract Method refactoring

Expected Behavior:

using System;

namespace ConsoleApp5
{
    class Program
    {
        static void Main(string[] args)
        {
            bool b = true;
            Console.WriteLine(NewMethod(b) ? b = true : b = false);
        }

        private static bool NewMethod(bool b)
        {
            return b !=
                true;
        }
    }
}

Actual Behavior:

using System;

namespace ConsoleApp5
{
    class Program
    {
        static void Main(string[] args)
        {
            bool b = true;
            Console.WriteLine(NewMethod(b) ? b = true : b = false);
        }

        private static bool NewMethod(bool b)
        {
            return b !=
                            true;
        }
    }
}
