This is the state for one of the incorrectly rendered pages from lib/template/template_node.js in the handleLoaded function. Layouts and templates are split up and joined later via the yield function in layouts.

layout_state.js

// Here if you look at the content field the template replaced 
// from yield(in the adapter.template field), it's different 
// than the content field from the template_state.js content field.
