This has existed all along (in the PHP parser as well as Parsoid * which is probably how the ref-in-ref hack works - because of how * parser functions and extension tags are procesed, #tag:ref doesn't * see a nested ref anymore) and this patch only exposes that problem * more clearly with the unpackOutput property. * * * Consider the set of extensions that * (a) process wikitext * (b) provide an extensionPostProcessor * (c) run the extensionPostProcessor only on the top-level * As of today, there is exactly one extension (Cite) that has all * these properties, so the problem below is a speculative problem * for today.

But, this * still doesn't necessarily guarantee that ordering doesn't matter. * It just guarantees that with the unpackOutput flag set to false * multiple extensions, all sealed fragments get fully processed. * So, we still need to worry about that problem. * * But, idempotence could potentially be a sufficient property in most cases. * To see this, consider that there is a Footnotes extension which is similar * to the Cite extension in that they both extract inline content in the * page source to a separate section of output and leave behind pointers to * the global section in the output DOM. Given this, the Cite and Footnote * extension post processors would essentially walk the dom and * move any existing inline content into that global section till it is * done.
