Bad html rendition

`<p>Hello</p><p>Trinity</p>` is currently text-mapped to `Hello p>Trinity `, then properly rebuilt.

However this can result in invalid highlighting.

```
  Standard mode
    with HTML content
<p>Hello and welcome to the real world, Neo.</p><p>Trinity will be there soon.</p>
[ { t: 0, h: 2, l: 3, c: false },
  { t: 42, h: 48, l: 4, c: true },
  { t: 72, h: 82, l: 4, c: true } ]
Hello and welcome to the real world, Neo. p>Trinity will be there soon. 
      ✓ should highlight multiple paragraphs 
<p>Hello</p><p>Trinity</p>
[ { t: 0, h: 2, l: 3, c: false },
  { t: 6, h: 12, l: 4, c: true },
  { t: 16, h: 26, l: 4, c: true } ]
Hello p>Trinity 
```
Ah yes sorry, I was thinking "At the end block elements", but didn't write that way.
