Rhythmdvl's failure to use Google maps 'search nearby'

Once upon a time I could put in an address/PoI, look at a map, then put in something like “restaurant near:address” and get a map that showed both the original starting point and the things I was interested in.

Now, when I try the ‘nearby’ function (whether manually in the search box or with the icon) the map zooms out, clears the original address marker and shows the set of searched for markers.

That’s fucking useless. The zooming out often loses the detail of where the original point was, and it’s damn hard to tell what’s nearer or easier to get to.

Is this a Google setting I accidentally switched? Could an add-on be interfering with the previous sanity of keeping the original marker? Is there some way of getting it back?
