This is an option for the visual html editor, ithas the feature to strip the urls base Href which is on by default which I see annoying. You can turn this feature off, edit these Templates:

HtmlEditor.html
HtmlEditorAdmin.html

search for this line

xinha_config.stripBaseHref = true;

You set the option value to true or false to turn it on or off:

To turn it off, this line should be:

xinha_config.stripBaseHref = false;

To turn it on, this line should be:

xinha_config.stripBaseHref = true;
