When the ListView has more items, it could be vertically scrolled, however, there is no UI for vertical scrollbar on Android.  The same can be observed with RadTreeView control.

Images loaded from memory stream behave strange - on iOS they don’t load immediately, only after list is scrolled and after that they start resizing and reordering randomly when scrolling; on UWP they load on initialization but have same problem with reordering.

Currently groupheader can be stretched by using GroupHeaderLength property instead rather than resolving it automatically.

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 control listen for changed to re-filter, so when any property is updated, there is a side effect on iOS - the entry used for editing loses focus.

With the previous release (2018.3.1) displaying many items (10000+) with groups and sorting took less than a second. With the latest release (2019.1.1) the time is increased to several seconds on the same device.

It seems the scroll position is calculated incorrectly in this case.
