The following code in ContainerNode::removeChild is bogus for a few reasons:
1. It happens after dispatchSubtreeModifiedEvent(). By that point, other scripts may have ran so it's too late.
2. This is not the only function that can remove DOM nodes from a tree.
auto* element = dynamicDowncast<Element>(oldChild);
if (element && (element->lastRememberedLogicalWidth() || element->lastRememberedLogicalHeight())) {
// The disconnected element could be unobserved because of other properties, here we need to make sure it is observed,
// so that deliver could be triggered and it would clear lastRememberedSize.
document().observeForContainIntrinsicSize(*element);
document().resetObservationSizeForContainIntrinsicSize(*element);
}
