The keyboard disappears and reappears when I change the focus

I have a list and when I delete an item, using the click or tap event, I set the focus on the next item to the deleted item, looking for id and with the focus () function. Then the keyboard disappears and reappears. How can I make this not happen and the keyboard is on top?

so I change the focus

setTimeout(()=>{
      let input =  
         document.getElementById(''+this.shoppingList.items[index]._id);
      let i = input.getElementsByTagName('input')[0];
      //console.log(input);
      i.focus();
    },1000)
