IconEditor is crashing with incorrect setFocus call

[raplemie]

Describe the bug
When using an editor with IconPicker type, there is a crash as this is attempting to call setFocus on a ref.

imports...
  StandardEditorNames as Editor,
  PropertyEditorParamTypes as EditorParam,
  StandardTypeNames as Type,

/** Create a property record to test, allowing editors to be defined. */
function createPropertyRecord(
  type: Type,
  value: any,
  editor?: Editor | PropertyRecord["property"]["editor"]
) {
  return new PropertyRecord(
    {
      valueFormat: PropertyValueFormat.Primitive,
      value,
    },
    {
      typename: type,
      name: "",
      displayLabel: "",
      editor: typeof editor === "string" ? { name: editor } : editor,
    }
  );
}
createPropertyRecord(Type.String, "icon-app-2", {
          name: Editor.IconPicker,
          params: [
            {
              type: EditorParam.IconListData,
              iconValue: "icon-app-2",
              numColumns: 2,
              iconValues: ["icon-app-1", "icon-app-2", "icon-apps-itwin"],
            } as IconListEditorParams,
          ],
        }),

Validate if this "always" crash or the test conditions caused it, if it always crash, validate if the component is really needed, or if the implementation could be completely changed...
