Close-on-select="false" property doesn't work [vue-multiselec] - vue.js

Question

When set close-on-select to false and searchable to true it isn't work correctly:
close-on-select=false searchable=true
but when set searchable to false it is work correctly: close-on-select=false searchable=false
Expected behaviour
Dropdown doesn't close on select.
Actual behaviour
Dropdown closes on select
I found the same question here, how to fix it: here
Here is my code:
<Multiselect
track-by="id"
id="students"
label="name"
v-model="form.users_ids"
:custom-label="nameWithRelation"
:options="optionUsers"
:multiple="true"
:close-on-select="false"
:clear-on-select="false"
:internal-search="false"
:preserve-search="true"
:hide-selected="true"
:searchable="true"
#search-change="(query) => asyncFind((search = query))"
#infinite-scroll="infiniteScroll"
/>
nameWithRelation({ name, relation_name }) {
if (relation_name) {
return `${name} (${relation_name})`;
}
return name;
},
asyncFind(query) {
const queryRouteWithDefaultPageSearch = {
...this.$route.query,
...{ page: 1 },
};
if (query) {
clearTimeout(this.delayTimer);
this.delayTimer = setTimeout(() => {
this.$store.dispatch(`${chat.STORE_ROOM_CHAT_KEY}/getListUser`, {
query: {
...queryRouteWithDefaultPageSearch,
keyword: (this.dataSearch.keyword = query),
},
mode: "search",
});
}, 500);
}
},
infiniteScroll(isIntersecting) {
this.currentPage++;
if (isIntersecting) {
this.$store.dispatch(`${chat.STORE_ROOM_CHAT_KEY}/getListUser`, {
query: {
page: this.currentPage,
},
});
}
},
