Some style system APIs (like StyleNewSubtree) don't deal with nested restyles really well (it'd be weird if StyleNewSubtree would end up styling not only that subtree but the whole document). To prevent breaking style system invariants, make sure to invalidate the style asynchronously using an early runner. This should ensure at most one frame of wrong metrics, but usually zero.
