I'm able to duplicate this on wikibooks in IE8 and IE9. Interestingly, the Wikibooks logo also disappears when I'm logged out.
The problem is caused by the notice from CentralNotice. Whoever put in the notice included <span class="plainlinks"> and did not close the span tag. That span tag can be eliminated entirely.
If the plainlinks class is desired for some reason, it can still be used by adding it to the list of classes for the a element:
class="external text plainlinks”
