ListView does not update on scroll when the source is NOT modified

Hello,

I ran into the following problem when using ListView in Forms.
Here is how the list looks when it is loaded for the first time:

Then, I scroll down to see other items with less stars:

Then, I scroll back up and the stars from down there are reused in the first cells, when they come back into view:

This issue is not present in iOS, only on Android. Haven't tested on WP.

If I change the item source or search for a contact, the list refreshes correctly.
If I scroll, it breaks again until the next manual refresh.
