/*
 * Tabs-Block (core/tabs): Unterlinien-Navigation statt Standard-Buttons.
 * Die aktive Linie ist ein eigenes Element (.wp-block-tab-list__indicator,
 * siehe tabs.js), das zwischen Tabs gleitet statt hart zu springen.
 *
 * Immer einzeilig: statt umzubrechen wird die Liste horizontal scrollbar
 * (wie Tab-Leisten in nativen Apps). is-scrollable-start/-end setzt tabs.js
 * abhängig von der Scrollposition, um nur dort einen Fade-Rand zu zeigen,
 * wo tatsächlich noch etwas verborgen ist.
