If you look at a revision for one post's history, you'll see all the posts after it in the thread, but they'll all have the text from that post! http://www.mediawiki.org/w/index.php?title=Thread:Project:Support_desk/Resize_external_image%3F&oldid=460434
The revision history probably has changed since your bug report, now it isn't an issue. If you click on the history tab of the URL you provided, it will display a history table with permalinks to each revision, which displays the thread with only the replies applicable at that time.
