Script Preparation code:

var ul = document.querySelector(`ul.general-tag-list`);
var div = document.querySelector(`div.general-tag-list`);
var weakmap = new WeakMap;
weakmap.set(div, [...div.children].map(x => x.value));
var total = 0;

Tests:

attr
let ids = Array(ul.childElementCount); for (let n = ul.firstElementChild, i = 0; n !== null; (n = n.nextElementSibling), (++i)) { ids[i] = n.getAttribute(`data-id`); }; total += ids.length;
val
let ids = Array(div.childElementCount); for (let n = div.firstElementChild, i = 0; n !== null; (n = n.nextElementSibling), (++i)) { ids[i] = n.value; }; total += ids.length;
weakmap
total += weakmap.get(div).length;

Run results for: <li> getAttribute('data-id') vs <data> value vs cache
