A boolean property parsed incorrectly

[svonidze]

Describe the bug
A boolean property parsed incorrectly, at the same time nullable boolean property - ok!

To Reproduce
https://dotnetfiddle.net/fwRMdJ

class Options
{
    [Option('a', "option1", Required = true)]
    public bool Option1 { get; set; }

    [Option('b', "option2", Required = false)]
    public bool? Option2 { get; set; }
}

class Program
{
    static int Main(string[] args)
    {
      args = "--option1 false --option2 false".Split(' ');
		
        return Parser.Default.ParseArguments<Options>(args)
        .MapResult(
          options => RunAndReturnExitCode(options),
          _ => -1);
    }

    static int RunAndReturnExitCode(Options options)
    {
        Console.WriteLine($"option1={options.Option1}, option2={options.Option2}");
        return 0;
    }
}

option1=True, option2=False

Expected behavior
option1=False, option2=False

Same root problem as I'm having?

#783 (comment)

You have a boolean option default=true. Does CommandLineParser not support setting booleans to false?

If you change option2 to default = true and run with --option2 false do you still get the same result?
