RoundRectangle Border is messed up when contains an Image with AspectFill

[ShariatPanah]

Description

so when you put an image inside of a Border with RoundRectangle set to it, the border itself in the corners doesn't show up correctly, let me show a screenshot: and this is my xaml code:

<Border
    HeightRequest="250"
    StrokeShape="RoundRectangle 40"
    StrokeThickness="2"
    Stroke="#e8ff8e"
    WidthRequest="100">
    <Image Source="{Binding Image}" />
</Border>

when i set the StrokeThickness to a large value like 20 the result is interesting, there is no curved border:

this behavior is just on Android, i tested with windows and it seems to work fine on small StrokeThickness but with a large value it would do a strange behavior too :) with small StrokeThickness on Windows:

with a large value, there you can see a gap between the border and the image:

in fact with a small StrokeThickness you can also see the gap, but its barely visible. didn't test on iOS so i don't know about it.

Steps to Reproduce

Just put an AspectFill Image inside of a Border and set the StrokeShape to RoundRectangle with some CornerRadius
