Ensure dialog is removed from history?

Please see code at http://cyclestreets.darkgreener.com/location/开发者_开发百科 - if necessary, go to a London, UK location to see some markers)

When you click on a marker, a jQuery mobile dialog opens.

If you then follow the 'Full link to photo page', then click Back, the page attempts to reload the dialog.

Is there any way I can remove the dialog from the history model altogether?

Thanks!
