was browsing exiting results This is most noticeable when viewing results in xephyr, and then opening a document in your regular session. But it could also be noticeable if downloading a new file completes while the user is in the overlay. This patch also moves the call to _displayMatchedItems() to _redisplay instead of making it in both _setDefaultList() and _doSearchFilter().
