Add support for options to the
scroll_to
method ofRenderedElementBacking
to define the desired final logical position inside the scrolling container for the vertical and horizontal axis. For the web platform this maps 1:1 to the options available in the corresponding DOM method scrollIntoView.The current behavior is pretty limiting as it is only possible to scroll such that the element appears at the top of the scrolling container. Adding these options will add more flexibility, covering common use cases such as a list where when the last element fitting the scroll container is active, you want to just visually advance to the next element, instead of moving the next element to the top of the container.
