 I'm using Firefox 23.0 on Ubuntu 12.04 and encountered the following
 problem:

 1. I navigate to http://www.openstreetmap.org and zoom into some area.
 2. In the address bar I get a permalink, say this one:
 http://www.openstreetmap.org/#map=8/58.898/25.587
 3. I switch to the traffic map and the link changes like this:
 http://www.openstreetmap.org/#map=8/58.898/25.587&layers=T
 4. I remove the "&layers=T" part in the adress bar and hit Enter, thus
 reproducing the permalink I had there before.
 5. I do _not_ get to the previous view / Mapnik layer, but instead the
 traffic map stays and the "&layers=T" in the address bar reappears.

 Alternative:
 4. I change the "&layers=T" to "&layers=C" (permalink to the cycle map).
 5. I do _not_ get to the cycle map, but instead the traffic map stays. The
 "&layers=C" and the "&layers=T" in the address bar reappears as soon as I
 change the map area.

 Expected behaviour: Entering a new permalink in the address bar should
 navigate to whatever that permalink describes.

 Actual behaviour: Entering those permalinks has no effect and the changes
 in the address bar are reverted.
