There are multiple things happening here which are interconnected: - We now use AbstractElement to refer to the source of a counter, which means we also need to pass that around to compute `content`. - Give AbstractElement new helper methods that are needed by CountersSet, so it doesn't have to care whether it's dealing with a true Element or PseudoElement. - The CountersSet algorithms now walk the layout tree instead of DOM tree, so TreeBuilder needs to wait until the layout node exists before it resolves counters for it. - Resolve counters when creating a pseudo-element's layout node. We awkwardly compute the `content` value up to twice: Once to figure out what kind of node we need to make, and then if it's a string, we do so again after counters are resolved so we can get the true value of any `counter()` functions. This will need adjusting in the future but it works for now.
