ListView: [iOS] Scrolls up/down on UI update

This can be reproduced in the SDK examples ->ListView -> Gestures -> CellSwipeEvents. 
1. Change the content of the items so that they have uneven height
2. Scroll down 
3. Delete an item by swiping
-> Expected result : The items re-arrange correctly
-> Actual result : The item is deleted but the ListView is scrolled up when the UI is updated

The issue could be reproduced in scenarios when:

- deleting rows with uneven height.

- scrolling the ListView it's item jumps to the top or bottom when clicked on this item and a layout is expanded.

Can this bug be fixed upon the next release? We've been dealing with the repercussions of it since well last year. 
This bug also occurs when you change a property value of the model in the list. For example, we can swipe to pin an item and once it pins, it jumps ALL the way up! 

To anybody trying to 'fix' it, you can set the listview property, 'IsItemsReorderEnabled' to 'TRUE' and it won't jump up anymore. It's not a good fix because if people hold onto the item for too long, it starts to move it to another position in the list.
