Conserve local links

[kazei92]

Currently, as I have understood, there is no way to put or conserve a local link like
<a href="#foo">Link to a local element</a>
<div id="foo"></div>

If I use editor.setContentHtml() and then print using the PrintPlugin, the local links do not persist either.

It would be nice to have it in order to have a navigation inside the document. Also, when Print to PDF, normally, the browser PDF engine keep them so it continues to work even in the generated PDF.
