<p>The ghost wiki excerpt eventually disappeared, even though I am not sure if this happened on its own or was a result of something me or @gung did (see <a href="https://stats.meta.stackexchange.com/questions/5124/should-we-do-something-about-mixed-design-tag?noredirect=1&amp;lq=1#comment15431_5141">here</a>).</p>

<p>I was not able to edit <a href="https://stats.stackexchange.com/posts/324506/edit">https://stats.stackexchange.com/posts/324506/edit</a> -- presumably such "abandoned" posts are locked which makes sense. The apparent bug was <strong>not</strong> that this abandoned post could be seen through the above link but that it was displayed as a wiki exceprt on the Tags page. Well, it is not anymore.</p>

<p>Anyway, I will mark this as accepted.</p>
