Jquery UI autocomplete select event not working in chrome 74

I am using Jquery UI autocomplete, on another dropdown selection an ajax get JSON data to load in autocomplete dropdown(#styleid), But options are not selectable in chrome. My chrome verson is 74.0.3729.131. While this code is working in firefox.

My Code is:

       var items = obj.style_options ;
        $( "#styleid" ).autocomplete({
                minLength: 0,
                source: function( request, response ) {
                    var string = $( "#styleid" ).val().replace(/,\s*$/, "");
                    var removeItem = string.split(',');

                    if(removeItem.length>0){
                        for(var k=0;k<removeItem.length;k++){
                            var cmpVal = $.trim(removeItem[k]);
                            if(cmpVal!=''){
                            items = jQuery.grep(items, function(value) { 

                              return value != cmpVal; 
                            }); 
                            }
                        }

                        //items = items.filter( function( el ) {
                            //  return !removeItem.includes( el );
                            //} );
                    }
                    //console.log(items);
                  response( $.ui.autocomplete.filter(
                    items, extractLast( request.term ) ) );
                },
                select: function( event, ui ) {

                    console.log(ui.item.value);
                    var terms = split( this.value );
                    terms.pop();
                    terms.push( ui.item.value );
                    terms.push( "" );

                    this.value = terms.join( ", " );

                  ///


                  ////
                  return false;
                },
                focus: function() {
                    $(this).data("uiAutocomplete").search($(this).val());
                }
              }).focus(function(){            
                    // The following works only once.
                    // $(this).trigger('keydown.autocomplete');
                    // As suggested by digitalPBK, works multiple times
                    // $(this).data("autocomplete").search($(this).val());
                    // As noted by Jonny in his answer, with newer versions use uiAutocomplete
                    $(this).data("uiAutocomplete").search($(this).val());
                });;`
