[iOS][9.0.30] View getting clipped while it shouldn't?

[JoviSimons]

Description

when updating to MAUI version 9.0.30 from 9.0.22, my Views are getting clipped. Below I provide a before and after update picture with the code. This is only on iOS, Android works fine. Really need this update since it fixes important issues for us.

Steps to Reproduce

Before update (version 9.0.22):

After update (version 9.0.30):

With HeightRequest 600:

Did something change with Views or how heights are measured in 9.0.30? Or what is the reason that it suddenly changes after update?

EDIT: removed code see sample project: https://github.com/JoviSimons/ViewSample

Link to public reproduction project repository

Version with bug

9.0.30 SR3

Is this a regression from previous behavior?

Yes, this used to work in .NET MAUI

Last version that worked well

9.0.22 SR2.2

Affected platforms

iOS

Affected platform versions

iOS 18.0.1

Did you find any workaround?

No workaround found yet, only setting the Height Request manually.

Hi @JoviSimons could you provide us with a sample project so we can investigate it further? Looking forward to your reply!

@JoviSimons your example is really convoluted.

I'm trying to replicate with a simple one like this, but it's working fine, so can you tell me what is gonna break this simple example?

void MainPage()
{
	var contentView = new ContentView();
	Content = contentView;
	Dispatcher.Dispatch(() =>
	{
	    contentView.Content = new ScrollView
	    {
	        BackgroundColor = Colors.Red,
	        Padding = 10,
	        Content = new Border
	        {
		        Stroke = Colors.Green,
		        Content = new Grid
		        {
			        VerticalOptions = LayoutOptions.Start,
			        BackgroundColor = Colors.BlueViolet,
			        MinimumHeightRequest = 300,
		        }
	        }
	    };
	});
}

@JoviSimons don't you have a mistake in your code?
https://github.com/JoviSimons/ViewSample/blob/master/ViewSample/MainPage.xaml.cs#L32
Shouldn't this be with ++?

grid.AddToGrid(createNewSection(isResize), row: rowCounter++);

This issue has been verified using Visual Studio 17.13.0 Preview 2.1 (9.0.30). Can repro on iOS platform. And 9.0.22 works fine.

@albyrock87 Yeah sorry, it's a fast stripped down version of the original code. The original code creates dynamic form layouts with sections and columns used in a no-code solution.
