/**
 * Repeat Tasks Today Bug #5976 E2E Test
 *
 * This test verifies the fix for GitHub issue #5976:
 * "Repeated tasks do not all appear in Today although they appear in the Planner & Scheduler"
 *
 * The bug: When multiple repeat task configs were due on the same day, some tasks
 * would fail to appear in Today because `addAllDueToday()` queried the store
 * immediately after dispatching `createRepeatableTask()` actions, before the
 * store had processed them.
 *
 * The fix: Added `await new Promise(resolve => setTimeout(resolve, 0))` after
 * `Promise.all(promises)` to yield to the event loop and allow the store to
 * process all dispatched actions before querying.
 *
 * Test strategy:
 * 1. Create multiple repeat task configs via Angular service calls
 * 2. Trigger addAllDueToday() by calling the service directly
 * 3. Verify ALL repeat task instances appear in the Today view
 */

   *
   * The fix adds an event loop yield after Promise.all() to ensure the NgRx store
   * has processed all dispatched actions before querying for the newly created tasks.
