webix multiComboFilter not filtering values with ","

Webix JS
#1

Hi i have my webix code like below


var grid2 = {
  view:"datatable",
  columns:[
    { id:"title", 	header:["Film title",{ content:"multiComboFilter" }] , fillspace:true},
    { id:"year",	header:["Released"]},
    { id:"votes",	header:"Votes", 	width:100 },
    { id:"rating",	header:"Rating", 	width:100 }
  ],
  scrollX:false,
  select:"cell",
   data: [
        { id:1, title:"The Shawshank,Redemption", year:1994, votes:678790, rank:1},
        { id:2, title:"The Godfather", year:1972, votes:511495, rank:2}
    ]
};				

webix.ui({
  padding:10,
  margin:10,
  rows:[
    {view:"label", label:"Multi-select filter in the DataTable"},
    grid2
  ]
});

now in the title dropdown when i try to filter the title “The Shawshank,Redemption” it is not getting filtered because of comma.

Now i want to select even though we have a “,” …How can i do that?
