Why does google use list in autocomplete instead of datalist?

Question

Google Chrome

<label>
            <strong>Pick a browser</strong>
            <input
                    autocomplete="off"
                    autocorrect="off"
                    list="browsers"
                    spellcheck="false"
                    type="search">
        </label>
        <datalist id="browsers">
            <option value="Microsoft Edge"></option>
            <option value="Firefox"></option>
            <option value="Chrome"></option>
            <option value="Opera"></option>
            <option value="Safari"></option>
        </datalist>

But they use a simple input and ul->li,
why?
