Why is this no longer necessary?

A few lines above, we have:

if (iter == locations_.end())
  continue;

So it doesn't seem to be necessary to check it again.

+    if (iter->second != new_location) {
       AccessibilityHostMsg_LocationChangeParams message;
       message.id = id;
       message.new_location = new_location;
