Title: BUG Rebuild internal jlayout structures on AJAX load.

jLayout does not track replaced elements. We have to trigger layout
algorithm manually on the parents of the replaced DOM so it can update
internal structures.

An example symptom is when a section of the CMS disappears or moves
after an AJAX load.
