I would like to be able to select a word, and unselect a word in a textarea programmatically. I am able to select a word in a textarea, by using the code below. However, the word remains selected after executing the removeAllRanges() and removeRange() method. Is there something I am missing to actually unselect the word? I would appreciate any assistance you can provide.

let textarea = document.getElementById("textarea");
let startPosition = 0;
let stopPosition = 15;
if (textarea.setSelectionRange) {
      textarea.setSelectionRange(startPosition, stopPosition);
    }
 // This line does not clear the selected word
 document.getSelection().removeAllRanges()

 // Does not clear the selection
 let s = window.getSelection();
  if(s.rangeCount > 1) {
   for(var i = 1; i < s.rangeCount; i++) {
    s.removeRange(s.getRangeAt(i));
   }
