Memory leak in LayoutInflater.Inflate method when using custom view in XML layout.

Android framework version

net10.0-android

Affected platform version

VS 18.4.11626.88 & 36.1.30/10.0.100

Description

The LayoutInflater.Inflate method can cause a memory leak if the XML layout contains a reference to a custom .net view. A regression has been observed in net10-android. The same code works correctly in net9-android.

Minimal repro in attachment. The example contains a reference counter. You can switch the project from net10-android to net9-android to see the change in behavior.

Steps to Reproduce

1. Create new net10-android application
2. Add custom view

internal sealed class CustomView : global::Android.Views.View
        {
            public CustomView(Context? context) : base(context) { } 
            public CustomView(nint javaReference, JniHandleOwnership transfer) : base(javaReference, transfer) { }
            public CustomView(Context? context, IAttributeSet? attrs) : base(context, attrs) { }
            public CustomView(Context? context, IAttributeSet? attrs, int defStyleAttr) : base(context, attrs, defStyleAttr) { }
            public CustomView(Context? context, IAttributeSet? attrs, int defStyleAttr, int defStyleRes) : base(context, attrs, defStyleAttr, defStyleRes) { }
        }

3. Add layout

<FrameLayout
	xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
	>

	<AndroidApp2.CustomView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
		/>
	
</FrameLayout>

4. Inflate it's somewhere

LayoutInflater.Inflate(Resource.Layout.test, null, false);

5. Observe memory leak
