Alert screen readers when items are selected on the map

Right now, when items in the side list are activated, screen reader users have no indication as to what happens on the map. Sighted users can see the marker come into focus with the popup activated. It would be helpful to provide a descriptive alert for screen readers.

Maybe we just need to set focus in addition to opening the popup?

That would work, I think.

Should be fixed in d4d7dbb.

When activating any of the links in the side panel, screen readers should now read the item title, it's latitude and longitude, as well as the "Opened" status. @katknow, could you test this with the usual screen reader and browser groups?
