Re: [csswg-drafts] [css-align-3] Specifying justiy-self on block-level boxes wrt floats (#9963)

@bfgeek I don't understand how `-webkit-center` is behaving here: https://software.hixie.ch/utilities/js/live-dom-viewer/saved/12378

<details>

```html
<!DOCTYPE html>
<label>margin-left<input id="margin-left" value="0" type="range" min="0" max="50" list="markers"></label><br>
<label>margin-right<input id="margin-right" value="0" type="range" min="0" max="50" list="markers"></label><br>
<datalist id="markers">
  <option value="0"></option>
  <option value="10"></option>
  <option value="20"></option>
  <option value="30"></option>
  <option value="40"></option>
  <option value="50"></option>
</datalist>
<div style="border: solid; overflow: hidden; width: 300px; text-align: -webkit-center">
  <div style="float: left; height: 100px; width: 100px; background: cyan"></div>
  <div style="float: right; height: 100px; width: 100px; background: magenta"></div>
  <div id="target" style="overflow: hidden; width: 50px; height: 50px; background: orange; margin-left:0; margin-right: 0;"></div>
</div>
<script>
var target = document.getElementById("target");
for (let prop of ["margin-left", "margin-right"]) {
  document.getElementById(prop).addEventListener("input", e => target.style.setProperty(prop, e.target.value + "px"));
}
</script>
```
