For the last couple of days, the map on the right-hand side of the /browse/changesets history view is not appearing. JavaScript error:

Error: Event.observe is not a function
Source File: http://www.openstreetmap.org/browse/changesets
Line: 315

Fails in Firefox 13.0.1, IE 9.0 and Epiphany 3.4.1. Confirmed across muleiple machines from multiple IP addresses. Last time I saw it working was probably no later than 27 June. Note that the individual changeset viewer /browse/changeset works as expected. The inline map script for the history page ends Event.observe(window, "load", init); while the individual changeset ends window.onload = init;.
