 * makes that div the containing block for position:fixed descendants
 * (CSS spec). gridstack's drag-helper has `position:fixed` and is positioned
 * by viewport coords (e.clientX/Y); when .rz-body scrolls the helper drifts
 * away from the cursor and drop coords go wrong.
 *
 * The identity matrix has no visual effect, so safely zero it out. !important
 * is required because Radzen sets it inline (specificity-wise, inline beats
 * stylesheet rules unless the rule is !important).

 * GridStack.init() has run and CSS vars are in place (lifts the mask below).
