FLUIDTEMPLATE variables may contain content elements (e.g. recursive
FLUIDTEMPLATE's) which may instantiate own TemplateViews
(e.g. StandaloneView).
A recursive StandaloneView will statically(!!) cache used TemplatesPaths
in \TYPO3Fluid\Fluid\View\Templates::resolvedFiles.

If StandaloneView is instantiated before, but the fluid layout path is
calculated after inner content objects are being rendering,
the altered statically cached `resolvedFiles` cache is used
and contains invalid layoutRootPaths.

Short term solution:
Defer the initialization of the StandaloneView (which flushes those
buggy caches) until all variables have been processed.
