MRUItems must correspond to an item in the editor's ValueList to have relevance.
When the MRUList property is set, the contents of the array is checked to verify that each items correspond
Note: The MRUList property is not applicable when the editor owner returns 'Suggest' or 'SuggestAppend' from the GetAutoCompleteMode method. Since the dropdown can only contain the filtered items in that scenario, MRU list functionality is suspended.
