I've managed to get it rendering correctly just by cleaning up the Markup a bit, which I'll email back to you. I just indented a code block and a bulleted list that were both nested within a numbered list. Still, it is disappointing that WikiPack just cut off a large part of the document, while Marked was able to display it. Testament to Brett Terpstra's awesome awesome coding prowess :) Seems that the Markdown parser which WikiPack uses is a bit more temperamental.
By the way, your use of <strike> tags is interesting. I wish there was native support for strikethrough text in Markdown, but there are a couple of alternatives that I've been contemplating. For example, Trunk Notes uses special syntax like {{check Buy Eggs}} to render an actual checkbox on the page with it's on/off state persistence stored in the page's metadata header. Task Paper on the other hand just uses hyphen lists to indicate todo items. I always use asterisks for bulleted lists personally, so I'm sorely tempted to implement something similar to Task Paper's todo list syntax as clickable checkboxes...
