Make relations available in fluid templates for content element preview
With v10 the new fluid based page module was introduced. It's now possible to directly add custom fluid templates
for the content element preview. To increase the value of this, the resolved records (especially for m:m fields) should be available in the fluid templates to reduce the need for ViewHelpers.
