Javascript error in embed.html when using a marker

[vincentdephily]

The code for embeding a map in an iframe is currently broken when a marker is included. In Firefox 35 I can see the zoom controls but no tile. Firebug says

ReferenceError: OSM is not defined
...arker(e.marker.split(","),{icon:L.icon({iconUrl:OSM.MARKER_ICON,iconSize:new L.P...

If you remove or mangle the 'marker' query string, it renders correctly (but lacking a marker).

BTW, this url is what you get when using "share ... HTML ... include marker" on osm.org. There are probably a lot of "how to find us" buisiness pages affected by this in the wild.
