Add a reftest that would fail in webrender before the corresponding fix landed. Ensures that there is an async zoom and that both the layout and visual viewports have async scroll offsets. To pass, we must apply each of the layout and visual offsets in their correct coordinate spaces.

<!-- Test that both layout and visual viewport scroll offsets are correctly applied.
|
|
|
|
An async scroll of 550 CSS pixels at 2.0x async zoom will ensure that
|
|
the visual viewport is scrolled beyond the bottom of the previous
|
|
layout viewport, meaning that the layout viewport is also scrolled so
|
|
that it contains the visual viewport.
|
|
|
|
Content should be scrolled by both the layout and visual offsets, in the
|
|
correct co-ordinate space for each, which should result the top half of
|
|
the div being scrolled out of view. -->
