Map this location on confirm page loses form data

After completing a registration form for an event, you're redirected to the confirmation page, which includes the event information and a link to map this location (if enabled). Clicking map this location directs to the map and a "done" button. Clicking "done" returns you to the event information page – not to the confirmation page – resulting in the loss of the user's registration details.

Short term solution is to edit: templates/CRM/Event/Form/Registration/EventInfoBlock.tpl and add target="_blank" to the map location link.

A more attractive solution would be to open the link in a modal (lightbox) window with just the map – not the full website page. Maybe with the addition of the jquery libraries we can do that more easily?
