Object.defineProperty() should maintain existing getter / setter if not overridden in the new descriptor. Currently, if the property is a has a custom getter / setter, and if the new descriptor only has a setter (or only a getter), it will clear the existing getter (or setter). This breaks search suggestions and the search button on www.iciba.com.
