/**
 * Updates category value references for flow elements visually enclosed by groups.
 *
 * A flow element is grouped only when it shares the group's diagram root and
 * is geometrically enclosed by the group. Consequently, visible children of an
 * expanded subprocess are grouped, while children of a collapsed subprocess
 * are not.
 *
 * Groups without a category value are auto-healed: if such a group visually
 * encloses an affected flow element a category value is created for it on the
 * fly, so that legacy diagrams (groups modeled without a category value) start
 * to categorize their contents as soon as they are interacted with.
