Почему появляется вертикальный скролл при overflow-x: auto?

Question

[sharpsss]

Всем доброго времени суток, в общем у меня есть table в котором есть поле с мультиселектом, и есть контейнер над этим table который я хочу сделать overflow-x: auto; собственно я так и сделал, но, когда открывается выпадающий список моего multiselect появляется вертикальный скролл хотя я не задавал overflow-y:auto; Вот код:

Код структуры

<div class="table_container">
      <UTable :headers="headers" :data="data">

        </template>
        <template #column5="{ entity }">
          <multiselect
            v-model="entity.type"
            :options="options"
            :searchable="false"
            :close-on-select="true"
            :show-labels="false"
            :allow-empty="false"
            placeholder="Pick a value"
          ></multiselect>
        </template>
      </UTable>
    </div>

он автоматически задается. Нельзя сделать auto/hidden/scroll по одной стороне и visible по другой.
