我使用ng-bootstrap进行弹出式广告。当鼠标悬停在div上时，它无法正常工作。
<div class="card" placement="right" ngbPopover="Vivamus sagittis lacus vel augue laoreet rutrum faucibus." popoverTitle="Popover on right" triggers="mouseenter:mouseleave">
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Maecenas id sapien ipsum. Morbi pulvinar est sed metus vehicula consequat. Proin et mi mauris. Nam faucibus arcu ac eros cursus semper. Aliquam erat volutpat.
</div>
