Screenshots
Initial memory usage
Memory usage after 10 calls to ScrollTo
You can see that around 14 MB where leaked
Reproduction Link
I have cloned the CustomCells sample from xamarin-forms-samples and slightly modified it to showcase the memory leak. You can get it from github : https://github.com/remi-appsolu/FormsListViewSample
Workaround
Not using RecycleElement fixes the issue but it is not recommended for performance.
