Screen not using the full width by default when on locked device orientation

[LennyIncrement]

Description

Hi,

I'm currently struggling with a MAUI Blazor Hybrid project...
If I lock the device orientation to landscape only then the screen is not using the full width (Simulated with iPhone 15 iOS 17.5 but also on a real iPhone device XR iOS 18.2.1).

It occures only on iOS.

What's really interesting is that if you allow portrait and then rotate the device to landscape then the width uses the full screen.
If you paint the background of the body to some other color than white you can see that the white area is part of the HTML-View

Edit: Add link to public reproduction project repository

Steps to Reproduce

1. Create a new project ".NET MAUI Blazor Hybrid App"
2. Framework: .NET 9 + Include sample pages
3. Go to the Info.plist and disable Portrait
4. Start the project with an iOS Simulator or a real device
