Title: Current selected element not displayed in newer jquery versions

... without jquery.migrate.
It's because it's using `that.$el.attr("selected") == "selected"` on single selects.
I have changed that to `$elm.prop('selected')` (same as on multi selects) and it works fine for me but I don't know why it was explicitly using another element variable and the `attr()` function for `selected`.
