Does by adding these UA Stylesheet rules, which we are missing, will fix these:

https://html.spec.whatwg.org/multipage/rendering.html#the-fieldset-and-legend-elements

```

legend[align=left i] {
  justify-self: left;
}

legend[align=center i] {
  justify-self: center;
}

legend[align=right i] {
  justify-self: right;
}

```
