How Scroll to Bottom of Editor with AutoSize="TextChanges" in ScrollView as the Size Changes

I am trying to use the new Editor property AutoSize="TextChanges" in a ScrollView and it works great until the Editor is so large that it gets cut off on the bottom as the typing continues. I've tried a view things using ScrollView.ScrollToAsync to get it to scroll to the bottom of the Editor on the Editor TextChanged event, but I can't seem to get it right. It either scrolls too far or not far enough.

How can I get the location of the bottom of the Editor in a ScrollView and have it scroll to that location in the ScrollView?

Thanks for your help.
