Aliaksandr Kalenik 9231b54d49 LibWeb: Pre-populate viewport in SVG subtree relayout ...

During SVG subtree relayout, position:fixed elements inside
<foreignObject> use the viewport as their containing block. Since the
viewport is outside the SVG subtree, it was not pre-populated in the
LayoutState, causing a VERIFY failure in ensure_used_values_for().

Fix this by unconditionally pre-populating the viewport node from its
paintable in relayout_svg_root().
