In forum integration, jumping to a particular post does not work well with collapsed wiki page
In vBulletin, you can jump to a particular post in a thread in any number of ways (today's post, most recent unread post, specific post number, etc). When wiki integration is enabled and that thread has a long wiki page with auto-collapse enabled, then that jump can get you to the wrong post because the jump does not account for the auto-collapse of the wiki page. For example, if a thread has 19 posts, 9 on the second page, and you jump to the 12th post, it might actually jump you to the 19th post as the wiki page collapses and pulls/scrolls the page up. You could argue that this may really be a browser problem, but it worsens the user experience.
The most reasonable solution to this is for the wiki page to open collapsed from the beginning if auto-collapse is enabled so that dynamic resizing doesn't occur. Then the jump will go to the right post. But I don't know if there is a technical limitation preventing this.
The other option is for the wiki page to offer a global or per-forum config option to disable auto-collapse if the request URL contains a jump to a particular post. Then VW can disable the collapse for that page and the jump will go to the correct post at the expense of the full wiki page loading - a fair trade off.
