Reported on English Wikipedia by User:Cryptic C62: "Upon opening the transclusion editor, or upon moving a component up/down using the arrows in the bottom left, the Wikipedia search box and accompanying buttons occasionally appear in front of the transclusion editor. The behavior does not occur consistently. Occurs in Firefox v21.0, cannot replicate in Chrome v28.0" See image: http://en.wikipedia.org/wiki/File:VE_Searchbox_Passthrough.jpg
This was caused by some issues with how the dialogs interacted with the Monobook skin, which have been subsequently fixed. Sorry for the slow triage.
