/**
 * Symbol Editor opened from a schematic session must show its libraries.
 *
 * Companion to `fpedit-from-eeschema.spec.ts`, and deliberately the WEAKER of the
 * two: this path is expected to be green already. It is here because
 * `SYMBOL_EDIT_FRAME::SyncLibraries()` carries the same latent defect shape the
 * footprint side had —
 *
 *     SYMBOL_LIBRARY_ADAPTER* adapter = PROJECT_SCH::SymbolLibAdapter( &Prj() );
 *     adapter->BlockUntilLoaded();          // ← no AsyncLoad() first
 *
 * — which `FOOTPRINT_LIST_IMPL::ReadFootprintFiles()` explicitly warns against
 * ("AsyncLoad() must be called before BlockUntilLoaded() to ensure library
 * loading is started"). `BlockUntilLoaded()` on a face that never preloaded
 * returns immediately with nothing loaded, and the tree comes up empty.
 *
 * It cannot fail TODAY because every route to the Symbol Editor already has
 * FACE_SCH running: `--frame=symedit` preloads it, and the only UI entry point is
 * eeschema's own toolbar (`ACTIONS::showSymbolEditor` is appended solely by
 * toolbars_sch_editor.cpp:201 — nothing in pcbnew/ references it). So this spec
 * pins the currently-working behaviour; it turns into a real regression guard the
 * moment a cross-kiface entry point is added.
 *
 * Same two traps as the footprint spec: assert on the wx FRAME LIST, not
 * `document.title` (which stays "… — Schematic Editor" even after a second editor
 * opens), and use the fileless `-/eeschema` route so no apps/sync is required.
