Hi! Its posible to know the position of a element inside a ‘ScrollView’ via ‘UNO’? I have a ‘ScrollView’ with many element that have relative ‘Height’ and I need to trigger a animation when the element appear on screen.

How can achieve this?

I had an approach playing with:

```auto
<WhileScrollable ScrollDirections="Down" Invert="true" />

```

But don’t work ass I expected.
