Bug 299306 – text-autospace: normal doesn't add whitespace between HTML elements

• Status: NEW
• Component: Layout and Rendering

[Zacky Ma]

Given this HTML:

```html
<p>学习<abbr>CSS</abbr></p>
```

And CSS:

```css
p {
  text-autospace: normal;
}
```

WebKit doesn't add whitespace between “学习” and “CSS”. Chromiums do add this. Here is the codepen for reproduce:

If this issue is fixed, it should resolve many failed test cases in WPT.
