Using choices.js causes an error in the console

Problem

Found that when using the choices.js library and clicking on one of the <select> options, the following error pops up in the console:

Steps To Reproduce

Steps to reproduce the behavior:

• Include choices.js on the page and create a <select> to be managed by it.

use_effect(move || {
    eval(r#"
const element = document.getElementById("ic-procedures-select");
const choices = new Choices(element);
    "#);
});

rsx! {
    select {
        id: "ic-procedures-select",
        option { value: "extended_session", "Запросить диагностическую сессию" },
        option { value: "default_session", "Запросить обычную сессию" },
        option { value: "hard_reset", "Перезагрузка блока (hard reset)" },
        option { value: "odo", "Чтение пробега" },
    }
}

• Buld the application and click to any select's option

Questionnaire

I'm interested in fixing this myself but don't know where to start.

I don't have time to fix this right now, but maybe later.
