BHV-9066: Reworked panel collapse/expand animation to use pure CSS

... instead of javascript measurements and style animator.

New technique uses no DOM measurements, no dynamically generated CSS, no repaints, and no re-layouts.

A double-inverse-transform is preformed on the breadcrumb frame and the panel-body frame to simulate the height+clipping effect.
