Nested ContentReferences Fusion is evaluated twice

[Sebobo]

Description

When using Neos.NodeTypes.ContentReferences:ContentReferences that reference elements that contain additional references the whole Fusion part incl. db queries of referenceNodes is executed twice and leads to almost twice the rendering time.

The problem disappears when converting the rendering from Fluid to AFX like in my Gist https://gist.github.com/Sebobo/48fcc490e7655f66208aaf0259b43859

Steps to Reproduce

1. Create text node on an empty page
2. Create reference to that node on second page
3. Create reference to the previous reference on third page
4. Check Fusion trace with http://github.com/Flowpack/Flowpack.Fusion.Tracing

Expected behavior

referenceNodes is only evaluated once

Actual behavior

referenceNodes is evaluated twice

Affected Versions

Neos: 4.3+
