When adding options to a question, the values that are entered in htmleditors are not saved.
This happens when one removes an option in between and not at the end.
So first an option is added at the end and then one is removed before that option.
The cause of them not being saved is because the values are not posted. (so are missing in the $_POST variable)
This only seems to happen with the CKEditor.
