Reduced test case:

<script src=../resources/text-based-repaint.js></script>
<script>
function repaintTest() {
  content.style.height = "200px";
}
onload = runRepaintAndPixelTest;
</script>
<div "container" style="overflow: overlay; height: 100px; border: solid">
  <div id="content" style="height: 50px"></div>
</div>
<style>* { min-width: 10000000000px; }</style>

The under-invalidation happens when the scroll corner appears very far from the visible viewport.

ClusterFuzz testcase 5800921660653568 is flaky and no longer crashes, so closing issue.

If this is incorrect, please add ClusterFuzz-Wrong label and re-open the issue.
