Border.StrokeShape is not currently being Garbage Collected

[marco-skizza]

Description

Hi

Possibly related to: https://github.com/dotnet/maui/issues/20163

When I add the following Xaml to a page, the page doesn't get garbage collected any more when navigating back:

        <Border>
            <Border.StrokeShape>
                <RoundRectangle CornerRadius="5" />
            </Border.StrokeShape>

            <Label Text="Border with StrokeShape is leaking" />

        </Border>

Steps to Reproduce

• Run the project
• Click Button and go back again multiple times
• Observe that ~Page2() never gets called

this is not only ios related. Same thing happen on Android in case you make a global Style for a Border (https://github.com/dotnet/maui/issues/20163)

something like this <Style x:Key="FooterStyle" TargetType="Border"> <Setter Property="StrokeShape"> <Setter.Value> <RoundRectangle CornerRadius="16,16,0,0" /> </Setter.Value> </Setter> </Style>

Verified this on VS 17.10.0 Preview 2.0(8.0.10). Repro on iOS 17.2 and MacCatalyst, not repro on Windows 11, Android 14.0-API34 with below Project: MauiPageMemory.zip

Seems to be fixed with .NET MAUI 8.0.20. Thanks!
