Aliaksandr Kalenik cda1d886df LibWeb: Fix not working Element::scroll_an_element_into_view()
Fixes following mistakes:
- "scrolling box" for a document is not `scrollable_overflow_rect()`
   but size of viewport (initial containing block, like spec says).
- comparing edges of "scrolling box" with edges of target element
  does not make any sense because "scrolling box" edges are relative
  to page while result of `get_bounding_client_rect()` is relative
  to viewport.
