Calling ref.focus() on component no longer forces scrollview to bring component into view

[aaronvega-msft]

Problem Description

We have a list of focusable elements within a scrollview, and we call ref.focus() on an element to force scrollview to bring it into view. This worked fine until this change came in: https://github.com/microsoft/react-native-windows/commit/571e6e65fc47b361c326fe4916f5df4c78bf943b

The element still gets focus, but scrollview no longer brings it into view.

An engineer from the RNW team suggested I revert the change and it fixed the issue. Can we get a fix for this?

Steps To Reproduce

1. Within a scrollview, create a list of focusable items.
2. Render the scrollview so that some items are scrolled out of view.
3. Call ref.focus() on any out-of-view item.

Expected Results

Scrollview should scroll to newly focused element.

We probably need to add code to call BringIntoView on the element - since programmatic focus doesn't appear to bring the element into view automatically.

Original change by Eric makes sense, although for your app reverting that with a patch is a fine workaround. Full fix would involve looking at what Andrew described above.
