steps to reproduce:

1) be in a network where zeroconf / avahi / mdns websites ("Nearby Sites") are announced
2) enter something in the url bar
3) observe the dropdown below the url bar -- from bottom to top, it shows %s search options (which is as intended), matching recently browsed sites (which is ok too), matching bookmarks (still ok), and all "nearby sites" (which this bug is about)

these virtual bookmarks should only be shown if they match. it seems they are not filtered (as opposed to showing up additionally), as when i enter a string that matches a "nearby" bookmark, it isn't shown twice.
