Standard help renders "Options" header when it is specified via optionListHeading even when there's only one hidden option

Code

import picocli.CommandLine;
import picocli.CommandLine.Command;
import picocli.CommandLine.HelpCommand;
import picocli.CommandLine.Model.CommandSpec;
import picocli.CommandLine.Option;
import picocli.CommandLine.Spec;

public class Main2 {
  public static void main(String[] args) {
    runMyTool("help");
  }

  private static void runMyTool(String... args) {
    CommandLine commandLine = new CommandLine(new MyTool());
    commandLine.execute(args);
  }
}

@Command(
    optionListHeading = "%n@|bold,underline Options:|@%n",
    subcommands = {HelpCommand.class}
)class MyTool implements Runnable {
  @Spec
  protected CommandSpec spec;

  @Option(
      names = { "--hidden" },
      hidden = true
  )
  String hidden = null;

  @Override
  public void run() {
    CommandLine commandLine = spec.commandLine();
    commandLine.usage(commandLine.getOut());
  }
}

actual output

Usage: <main class> [COMMAND]

Options:
Commands:
  help  Displays help information about the specified command

expected output: (without "Options:" line)

Usage: <main class> [COMMAND]

Commands:
  help  Displays help information about the specified command

bug summary

When Command has only hidden options and optionListHeading is specified for that command then option list heading is always printed by help subcommand.

EDIT:
picocli version 4.2.0
