Imagine I'm blocked on enwiki but have my interface language set to zh, so I see http://en.wikipedia.org/wiki/MediaWiki:Blockedtext/zh with $x populated. Of course sysops are expected to write block message in this wiki's content language so $2 is in en, but it's not wrapped in <span lang="en" dir="ltr"></span>.
If this is done, and bug 37617 is done (and instead of disabling conversion, use LanguageXx for <span lang="xx">), bug 34832 may get a better resolution.
