[🐛 Bug]: Edge driver -inprivate option doesn't work in application mode (--app==http*)

[mkca20]

What happened?

In edge v 133 I was able to start Edge in private mode and application mode at the same time. In version 134 it is not possible.
Please check below screen to see how it works. (script in section how to reproduce)

How can we reproduce the issue?

var edgeDriverService = EdgeDriverService.CreateDefaultService(driverFolder);
            var edgeOptions = new EdgeOptions();
            var input = "";
            while (true)
            {
                input = Console.ReadLine();
                if (string.IsNullOrEmpty(input) || input.Equals("q"))
                {
                    break;
                }
                edgeOptions.AddArgument(input);
            }

            edgeOptions.AddArgument("-start-maximized");
            var driver = new EdgeDriver(edgeDriverService, edgeOptions);
