Kendo React - External filter - Delay onChange while typing in the first DropDownList

Hi, Jason,

By default, the `onChnage` event of the filter is triggered only on first key press or when the user is navigating through the items via the arrow keys. If it will be applicable to your scenario, you can add the desired timeout around the `setFilter` call, but this will slow down the highlighting of the target item as well:

  const onFilterChange = (event: FilterChangeEvent) => {
    setTimeout(() => setFilter(event.filter), 1000);
  };

You can see a sample illustrating this approach in the - https://stackblitz.com/edit/react-frxexq-mkctyb?file=app%2Fmain.tsx
