harvesthq/chosen — Issue #510: optgroup not showing on list update

When you dynamically change a Chosen manipulated multi-select, inserting whole optgroups with nested options while the select box is open, Chosen won't render the "display: list-item" CSS property into the optgroups. This makes optgroups labels invisible.

The validation for empty optgroups should run every time the list is updated.
