Here, when you click on dropdown filter, it gets closed (for android devices) The dropdown is implemented in such a way that if you click outside the dropdown it gets closed.

let filterElt = this._list.shadowRoot.querySelector("[part=filter]");

if (filterElt) {
  filterElt.addEventListener("click", (e) => {
    e.cancelBubble = true;
  });
}

this._list.addEventListener("mousedown", (e) => {
  e.cancelBubble = true;
});

Tried using preventDefault(), stopPropagation() and adding touchevents to filter element
