When you open the web inspector, the page changes layout & it looks correct, presumably because the web inspector causes a reflow.

I haven't looked deeply into the cause or what exactly causes this, but here's a smaller testcase:

<style>
.test {
  display: block;
  overflow: hidden;
  width: 300px;
}
.inline {
  display: inline;
}
.float, .clear {
  display: block;
  overflow: hidden;
  height: 3px;
  width: 100px;
  background: #f0f;
}
.clear {
  background: #0ff;
}
</style>
<div class="test" style="direction: ltr;"><div class="inline" style="direction: rtl;"><div class="float" style="direction: ltr; float: left;"></div><div class="clear" style="direction: ltr; clear: right;"></div></div></div>

I had to disable imported/w3c/web-platform-tests/css/css-logical/logical-values-float-clear-reftest.html in bug 218087 because of this bug.

I linked it here in the TextExpectations file, so it's worth testing again here if it's still broken.

This seems to be fixed in STP165 using attached test case from Alan and matching with Chrome Canary 113 and Firefox Nightly 113.

I think we enable test referred by Tim in Comment 04 now.
