Race condition with loadOption set

[PlkMarudny]

I retrieve data using loadOption. If I press 'Enter' (to select) before the list opens, the component crashes:

in filter.js:

 let filterResults = items.filter((item) => {
        let matchesFilter = itemFilter(item[label], filterText, item);
        if (matchesFilter && multiple && value?.length) {
            matchesFilter = !value.some((x) => {
                return x[itemId] === item[itemId];
            });
        }

        return matchesFilter;
    });
