AbsoluteLayout with SizeProportional not working

[JavierFajardoSecanda]

Description

When I use the AbsoluteLayout component and define the LayoutFlags property as SizeProportional, my application crashes.

This is the error message: Message = "Layout cycle detected. Layout could not complete."

The application works if I add to the AbsoluteLayout component the property MaximumHeightRequest. But, I don't know why I have to add this property and why it's not working without this.

Steps to Reproduce

1. Create a new MAUI project.
2. Create one view (MainPage) and a view model (MainPageViewModel)
3. Adding an AbsoluteLayout component to the MainPage view
4. Launch the application and check it's not working and we can see the error with the message: "Layout cycle detected. Layout could not complete."
5. Add the MaximumHeightRequest property to the AbsoluteLayout component (For instance: MaximumHeightRequest="1000")
6. Launch the application again and check it's now working

Can repro this issue at Windows platform on the latest 17.10 Preview 6(8.0.20&8.0.21).

Can also confirm, that it also happens with a StackLayout at refreshing by ViewModel

I found my bug, when trying in Debug running, and the App Started on my first Desktop. Then i switch it to a bigger Screen (other Desktop). After switching i reloaded from ViewModel by OnPropertyChanged Trigger and it crashed to App.g.i.cs UnhandledException: "Layout cycle detected. Layout could not complete."
