Bug 262367

Given the following HTML and CSS in Safari you will not see the `#pop` div. It is not clear to me whether this is right or not (spec wise), but it is different than Firefox and Chrome's handling. If you remove the `position: relative` or change it to anything else besides `position: sticky` you *will* see the green box on all browsers.

```
<style>
table {
  overflow-y: hidden;
}

#wrap { 
    /* The presence of this relative changes the output in Safari 16.5 */
  position: relative;
}
#pop {
  position: absolute;
  top: 30px;
  left: 0;
  width: 200px;
  padding: 10px;
  background: green;
}
</style>

<table>
  <tbody>
    <tr>
      <td>
        <div id="wrap"> Hello
          <div id="pop"> Should you see me?
        </div>
      </td>
    </tr>
  </tbody>
</table>
```
