MainDisplayInfo reports page size instead of screen size in .net 8

[mmiller-d8]

Description

After upgrading to .net 8, DeviceDisplay.Current.MainDisplayInfo is reporting the page height and width instead of the screen. If you get the height and divide it by the density on an iPhone 15 pro, it reports 852 which is the same size as the page. In .net 7, it reported the actual screen size. Which is what I would expect from MainDisplayInfo.Height - rather than the useable space.

Ideally, I could get either the actual display height or the page height. It would also be nice to get the height of the bottom and top gutters individually.

However, the main issue is that this reported one number in .net 7 and a different number in .net 8 and I don't have a clear solution for getting the actual screen height.

Steps to Reproduce

Call DeviceDisplay.Current.MainDisplayInfo.Height and compare it to the height of the page.

    var pageHeight = this.Height;
    var screenHeight = DeviceDisplay.Current.MainDisplayInfo.Height / DeviceDisplay.Current.MainDisplayInfo.Density;
    var screenHeight2 = DeviceDisplay.MainDisplayInfo.Height / DeviceDisplay.MainDisplayInfo.Density;

    Console.WriteLine(pageHeight == screenHeight && pageHeight == screenHeight2);

Is this a regression from previous behavior?

Yes, this used to work in .NET MAUI

Last version that worked well

7.0.101

Affected platforms

iOS, I was not able test on other platforms

Affected platform versions

iOS 15

Did you find any workaround?

Not really, no. I can't easily get the size of the top and bottom gutter and the navigation bar. If I could get those, I could do the math myself.
