[TYPO3-english] internal links in RTE become external links

[Jacco van der Post]

Hi,

On my installation 7.3 I have internal page links in the RTE seem to 
become external links. This causes also no RealUrl transformation.

So if I save a content element the link becomes

<a title="Opent interne link in huidig scherm" class="internal-link" 
href="http://beta.bla.nl/?id=50" rtekeep="1" 
data-htmlarea-external="1">Link</a>


1. Why do rtekeep="1" data-htmlarea-external="1" get added?
2. How can I fix this?

thanks
