Device Idiom detects Windows as tablet

Description

Using DeviceInfo or the OnIdiom markup extension detects Windows as tablet. I’ve seen these: https://github.com/dotnet/maui/issues/4351 https://github.com/dotnet/maui/issues/2423 https://github.com/dotnet/maui/issues/5769

But the issue still occurs. See:

Steps to Reproduce

1. Create a new .NET MAUI app
2. Use DeviceInfo.Current.Idiom or the OnIdiom markup extension
3. Run on Windows
4. Observe that the detected idiom is tablet

Update: I did this initially on my laptop, which has a touch screen. Ran it again on my desktop (which doesn’t have a touch screen) and got the expected result:

So I’m guessing you’re using the presence of a touch screen to distinguish between desktop and tablet.

If this is intentional (i.e., if you consider a Windows computer with a touchscreen to be a ‘tablet’), then I think the documentation should reflect this. But I also don’t think this is the right approach; while it may be useful to distinguish between touch and non-touch devices, I don’t think the device idiom is where developers expect this to be distinguished.
