In live workspace this just renders a the content.
For logged in users with access to the Backend this also adds the attributes for the RTE to work.

@param NodeInterface $node The node of the content element. Optional, will be resolved from the Fusion context by default.
@return string The rendered property with a wrapping tag. In the user workspace this adds some required attributes for the RTE to work
