Do you really need the IsString() ? 

If there are layout tests passing params that they should those should be fixed.

Fixed layout tests. 
In this case I think we don't need |args->PeekNext().IsEmpty()| as
|getPointerType()| will do the check and return true if empty.

This will match the usage in other places.

+    if (!getPointerType(args, false, event.primary_pointer_type))
+      return;
+  }
