Xamarin Forms ListView Images Sometimes Displays, Sometimes Doesn't (UWP)

问题

I have a ListView in which I'm displaying the same image (chevron_right.png) in each of the rows.

On load, none of the images show.

However, when I navigate away from that page via Navigation.PushAsync() and then return back to the original page via Navigation.PopAsync(), the images display as they should.

Simplified version of my code:

<ListView x:Name="MyList">
    <ListView.ItemTemplate>
        <DataTemplate>
            <ViewCell>
                <StackLayout Orientation="Horizontal">
                    <Label Text="Hello">
                    <Image Source="chevron_right.png" HeightRequest="30" WidthRequest="10">
                </StackLayout>
            </ViewCell>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

This is occurring on Universal Windows Platform. Any help/incites/suggestions would be greatly appreciated. Thanks!

This is a logged bug (https://bugzilla.xamarin.com/show_bug.cgi?id=36097).

version 1.5.2.6469-pre1 is the last version where the issue does not occur.

Workaround that was functional for my purposes: Place Image into a <Grid> and set the ColumnDefinition Width = "Auto" for the column that is containing said Image.

Hope this gets fixed soon!
