Text element with nested element that needs to wrap, overlaps layers in sketch
When a text element has child elements like a link or span, and needs to wrap, the text layers are placed on top of one another.

**html-sketchapp version:** `4.3.0`

**minimal example:** 

```html
<p>
  <a href="/contact-us">Visit our Contact Us page</a> to find retail centres, opening hours and more.
</p>
```

I've seen the same behaviour with divs and spans too:

```html
<div>
  Lorem ipsum dolor ist amet <span>integer velit luctus hac nunc adipiscing</span> eget enim consectetur maecenas libero iaculis.
</div>
```
