Describe the issue

Hi,

Since Bootstrap v5.2.0, the tooltips never close when they are initialized with selector option. It worked fine under Bootstrap v5.1.3. So, I think there is a regression.

HTML:

<div id="btn-box" class="btn-group m-5">
  <button class="btn btn-lg btn-primary" title="Label 1">Button 1</button>
  <button class="btn btn-lg btn-secondary" title="Label 2">Button 2</button>
</div>

JavaScript:

new bootstrap.Tooltip('#btn-box', {
    selector: '[title]'
});

Reduced test cases

The tooltip is hidden when the mouse leaves the element	Version	selector option	CodePen link
