Reproduction path:

-In the console (https://cms.demo.onehippo.com/console) at /hippo:namespaces/hippostd/html/editor:templates/default/root at 'Xinha.config.toolbar' add 'htmlmode' and save this.

Use IE7 (or IE8/9 in compatibility mode) and go to https://cms.demo.onehippo.com/

• Open a new document (type doesn't matter; as long as it has a html-field in it).
• Type something in the html field.
• Click on htmlmode
• You will now see a bunch of html code (see htmlcode.png)
• Go back to normal view
• Select some text and create an internal document link.
• Select some other text and create an internal document link.
• The lay-out of the document picker is broken
