it('should be accessible', async done => {
      const advancedSearchElement = getAdvancedSearchElement();
      getResultsColumn().appendChild(advancedSearchElement.el);

      advancedSearch.open();
      const axeResults = await axe.run(getRoot());
      expect(axeResults).toBeAccessible();
      done();
    });
  });

      const facetElement = getFacetElement();
      getFacetColumn().appendChild(facetElement.el);
      await afterDeferredQuerySuccess();
      (get(facetElement.el) as Facet).facetSearch.focus();
      await afterDelay(1000);
      const axeResults = await axe.run(getRoot());
      expect(axeResults).toBeAccessible();
      done();
    });

const showSuggestions = (omniboxElement: Dom) => {

    };

export const isInit = () => {
