Test case

The attached test case looks like the following:

```
<div id=div contenteditable=false tabindex=0>
  <a href="#yer">Yer</a>
</div>
<script>
div.addEventListener('focusin', (evt) => {
  console.log(evt.target);
});
</script>
```

Clicking the link in Firefox or Chrome triggers a `focusin` event with the target set to the <a> element.

In Safari 16.5 and TP, the `target` is set to the `<div>`.

Furthermore, without the `tabindex=0`, no focusin event is dispatched in Safari, although it is in Firefox and Chrome.
