Options elements dynamically created by Knockout.js options binding does not have offsetTop value

I am working on a existing add in which we are using Knockout.js for data binding. One of the new requirements is to be able to automatically scroll to a specific option (determine prior by a given criteria) in the <select> list when you cick on the button to show the dropdown

Generally if you have hardcoded <select> list with <options> this is pretty easy to achieve by using the scrollIntoView() function. The problem for me is that I noticed that all the <option> elements created with Knockout options binding hasoffsetTopproperty of 0. ThereforescrollIntoView()` always scroll to the top of the list.

I am wondering if there is any solution - either to manage to assign offsetTop values to the <option> element or some other way to scroll to specific option in the list. I can not share the exact code , so I am giving some pseudo code:

HTML

<div id="container">
    <p style="margin-top: 100px;">
        Your country:
        <select id="select2" data-bind="options: availableCountries,
                       optionsText: 'countryName',
                       value: selectedCountry,
                       optionsCaption: 'Choose...'"></select>
    </p>

    <div data-bind="visible: selectedCountry"> <!-- Appears when you select something -->
        You have chosen a country with population
        <span data-bind="text: selectedCountry() ? selectedCountry().countryPopulation : 'unknown'"></span>.
    </div>
</div>

JS

var Country = function (name, population) {
    this.countryName = name;
    this.countryPopulation = population;
};

var viewModel = {
    availableCountries: ko.observableArray([
        new Country("UK", 65000000),
        new Country("USA", 320000000),
        new Country("Sweden", 29000000)
    ]),
    selectedCountry: ko.observable() // Nothing selected by default
};
$(document).ready(
$('#btn').click(function () {
        $('#select2').val("USA")[0].scrollIntoView();
    });

    ko.applyBindings(viewModel);

});

Thanks in advance
