Test case

Absolutely positioned elements should be displayed on top of statically positioned elements.

When there is nested overflow:auto, the positioning is sometimes strange.

In the following example, ELEMENT-A should be displayed on top of and potentially cover ELEMENT-B.

<div style="position: relative; overflow: auto">
  <div style="position: absolute" ELEMENT-A>
    SHOULD BE DISPLAYED ON TOP
  </div>
  <div style="overflow: auto" ELEMENT-B>
    SHOULD BE DISPLAYED UNDERNEATH
  </div>
</div>


The attached test case should only show a green viewport, but in affected browsers red text is visible.

Affected: Safari on iOS 17.0.3.

NOT affected: Safari on iOS 16.6.1.
