Xamarin.forms: [Android, PCL] - ImageLoaderSourceHandler: no se pudo recuperar la imagen o los datos de la imagen no eran válidos

Descripción

• En Android, usando los formularios más recientes y un proyecto PCL ... un ImageCell XAML con un ImageSource codificado may timeout y devuelve un error.

• Parece funcionar como se esperaba con las soluciones estándar de .NET o compartidas

• Solo probado en simulación

<ImageCell
    ImageSource="https://www.xamstatic.com/dist/images/pages/platform/visual-studio-icon-uHIZMvQl.png"
    Text="{Binding Name}"
    Detail="{Binding Job}">
</ImageCell>

...
[0:] ImageLoaderSourceHandler: Could not retrieve image or image data was invalid: Uri: https://www.xamstatic.com/dist/images/pages/platform/visual-studio-icon-uHIZMvQl.png

Pasos para reproducir

1. Usando el repositorio a continuación, cargue la muestra de PCL
2. Correr
3. Debería ver una lista de ImageCell con el icono de Visual Studio
4. Verifique la salida en busca de error y tiempo de espera
5. ¿No ocurrió el error? Desinstale la aplicación y vuelva a intentarlo.

Comportamiento esperado

Todas las imágenes se cargan, como lo hacen en las soluciones estándar .NET y compartidas.
