HTML Widgets; widget.UI.ParametersHost; "Limit To List" not supported for List type Parameters

A List-type Parameter that was configured to "Limit To List" was not respecting this flag when viewed in a ParametersHost control such as on the Client Edit form, User Defined page. Any value could be typed into the list.

The same was true of Parameters under finPOWER Connect Cloud, e.g., the "Order By" Parameter available on most Reports.
