Odd behavior on iOS with ScrollToPosition.Center

[Unknown]

Hi,

we are seeing an odd behavior of SfListView.ScrollTo() on iOS.

What we like to achieve is, that the list view is scrolled to the currently selected item. If this item is e.g. the first of the list and we use ScrollToPosition.Center, the first item is indeed centered in the list view - what is somewhat unexpected.

One would expect the list view having the first item nevertheless at the top, as this is with Android.

Using ScrollToPosition.MakeVisible does not yield this behavior, but we would prefer .Center for our scenario.

Please find attached a small sample to reproduce this.

I consider this a bug. Or am I doing something wrong?

Regards, Ulrich
