🐞 bug: driver.WindowHandles behavior not limited to the app launched

[kinland]

Is there an existing issue for this?

• I have searched the existing issues

Appium Version

3.2.2

Appium Host Type

Command Line

Current Behavior

I'm in the process of switching from WinAppDriver to NovaWindows Driver... This line behaves totally differently:

driver.SwitchTo().Window(driver.WindowHandles.First());

In WinAppDriver, that would be the app that you launched. But with NovaWindowsDriver, driver.WindowHandles appears to list ALL window handles, not just the ones related to the app that was launched!

Expected Behavior

Behavior should match what happened in WinAppDriver unless there's good reason to depart from that. In particular, driver.WindowHandles should not have visibility into totally unrelated applications.

Minimal Reproducible Example

// C#
using OpenQA.Selenium.Appium;
using OpenQA.Selenium.Appium.Windows;

namespace Tests
{
    [TestFixture]
    public class MinimalAppiumTest
    {
        
        [Test]
        public void TestNotepadLaunch()
        {
            var options = new AppiumOptions();
            options.AddAdditionalCapability("platformName", "Windows");
            options.AddAdditionalCapability("appium:automationName", "NovaWindows");
            options.AddAdditionalCapability("appium:app", @"C:\Windows\System32\notepad.exe");
                        
            WindowsDriver<WindowsElement>? driver = null;
            driver = new WindowsDriver<WindowsElement>(new Uri("http://127.0.0.1:4723"), options, TimeSpan.FromMinutes(1));            
            Assert.That(driver.WindowHandles, Has.Count.EqualTo(1));
                
            driver?.Quit();
        }
    }
}

Further Information

Simply opening notepad as described above results in something like:

TestNotepadLaunch (2s 966ms): Error Message: Assert.That(driver.WindowHandles, Has.Count.EqualTo(1))
Expected: property Count equal to 1
But was: 17

Hello, this is how I initially wrote the driver as I needed to switch to another app mid-test quickly, before intending to publish the driver.

I will put this behind a capability and will use WinAppDriver's default behaviour to ensure compatibility.
