Bug userview html page editor

The html editor in the userview is showing strange behaviour.

In the community edition when I insert custom html, in a html page, the lines beginning with <link rel="stylesheet" type="text/css" href="/test.css"> are being deleted, after saving the page.

In additon, my java script block <script type="text/javascript" src="test.js"></script> is put consequently beween paragraph tags, after saving. The same happens when I add a div tag with the name parameter, then only the name parameter is deleted, after saving.

When I would add the same html markup into a custom html element, in a form, it works fine.

Upon copying the same html markup into a userview, in the enterprise edition, it works fine though.

The html editor in the userview also messes up my code when I switch from corporati theme to the standard theme back to the corporati theme.
