[iOS & Mac] Gradient background size is incorrect when invalidating parent

[RanjithkumarSyncfusion]

Description

When invalidating a parent, gradient applied to the child fills the entire screen.

In my example, I have a Grid with 2 Rows(40,*) and loaded a button as first row with LinearGradientBrush. When calling Grid.InvalidateMeasure(), the gradient size fills the entire screen.

Steps to Reproduce

1. Run the attached sample.
2. Click anywhere outside the Button. Gradient.zip

Did you find any workaround?

Yes Rename the gradient relevant layer name to skip size updating for this particaluar layer alone. private void ButtonLoaded(object? sender, EventArgs e) {

if IOS

        if(sender is Button button && button.Handler != null && button.Handler.PlatformView != null && button.Handler.PlatformView is UIKit.UIView platformView)
        {
            if(platformView.Layer != null && platformView.Layer.Sublayers != null)
            {
                if(platformView.Layer != null && platformView.Layer.Sublayers != null)
            {
                var layer = platformView.Layer.Sublayers.FirstOrDefault(x => x.Name == "MauiBackgroundLayer");
                if( layer != null && layer is CALayer gradientLayer)
                {
                    gradientLayer.Name = "GradientLayer";
                }
            }
            }
        }
