Tags inside html properties break column_data_type=rendered_html

Example: https://jsfiddle.net/pfnmvaex/

The rendered html is:

<abbr title="hello<br>world">some_text</abbr>

The result, as can be seen in the JSFiddle above:

Hi m417z

column_data_type: 'html',
text_data_delimiter: " world ",

[m417z]

Using column_data_type: 'html' has a different use case. Change the render function to the following and see the difference:
return '<abbr title="hello<br>world">Mr. ' + x + '</abbr>';

As for the issue itself, I suspect that it might actually be a limitation of DataTables, not the plugin. I didn't investigate too much since I found a workaround for my case.
