Description

Attempting to mark code inside of a code block will misplace the mark closing tag, placing it before the next token starts, and if it is added after the last token ends it needs a whitespace to get added, other wise it is included in the last token. Usually the string-literal token is the easiest to reproduce this with.

Examples:

```ruby
<^><% %><^>
<% %>
```

```ruby
<^>to: ""<^>
```

```js
<^>const test = `hello<^>
world`;
```

In the last example we can see the mark closing tag is closed before the string literal starts:

Clear the textbox
Paste one of the above examples inside of the textbox

Expected behavior

Text inside of the <^> marking token gets marked in the resulting code block

There are a whole set of dedicated test cases for it: https://github.com/digitalocean/do-markdownit/blob/master/modifiers/prismjs.test.js (specifically the HTML preservation block of tests)
