@keypress.prevent="shortDescriptionInput"

function shortDescriptionInput(event) {
  // Variables
  const value: string = event.target.value;
  let key: string = event.key;
  if (key === "Enter") key = "\n";
  const selectionStart: number = event.target.selectionStart;
  const selectionEnd: number = event.target.selectionEnd;

  // Check if change exceeds max height
  event.target.value = value.slice(0, selectionStart) + key + value.slice(selectionEnd);
  if (event.target.clientHeight < event.target.scrollHeight) {
    event.target.value = value;
  }

  const cursorPosition = event.target.value.length - value.length + selectionEnd;
  event.target.selectionStart = cursorPosition;
  event.target.selectionEnd = cursorPosition;
}
