Remove resource container restriction in SVGContentContainer::Layout
We're no longer bound by a subtree layout scope, and will only perform
non-descendant layouts for markers - which we have ad-hoc cycle solving
during layout in place for as well as the regular mechanism. Layout of
of the non-descendant markers are also never forced. This can mean that
some marker resources are layouted twice under the right circumstances.
Not allowing these layouts means viewport changes (and similar) won't
propagate into resources, causing breakage like in the referenced bug.
