We only have code to handle translated select drop downs, we don't have any code to handle scaled (or other transforms) select drop downs. There might be a bug on file for this already.

When you fill out an <input /> the autocomplete values (previous entries) are also shown at an invalid location.

That code is different and a fix will probably be separate from a fix for this bug.
