Space before super- and subscripts.

1. Select any document in the CMS and click edit.
2. In any rich text field add "test²" (test+superscript 2).
3. Clik save.

Expected output: after saving the document the text is still "test²".

Actual output: after saving the document the text becomes "test ²" (with space inbetween).

Workaround:
1. In the console go to: "/hippo:configuration/hippo:frontend/cms/cms-services/htmlCleanerService".

2. Change the value of the property "serializer" (now it is "compact") to an empty string "".

2. Restart the server.
