The view parameters available in the full view of node that is executed through a Twig pagelayout are not correctly set.

The $view_parameters variable always contains the default values (no matter the view parameters set in the URL) + a viewbaseLayout key. For instance, on /(offset)10/(foo)/bar, {$view_parameters|dump( true(), 2, 'text' )} returns:

offset (boolean=false)
year (boolean=false)
month (boolean=false)
day (boolean=false)
namefilter (boolean=false)
viewbaseLayout (string='EzPublishCoreBundle::viewbase_layout.html.twig')
