[Android] CachedImage doesn't load in SFListView until after scrolled off screen

See original GitHub issue

I’m finding some strange behavior whereby when I load a CachedImage into an ItemTemplate within an SFListView, I see a blank space where the image should be until I scroll.

Here’s a template

<ContentView xmlns="http://xamarin.com/schemas/2014/forms"
