// Name: loadAlgorithmRejectPromisesWhenPausing
// Case: step1: create an element with its paused member to be fause and networkState to be NETWORK_NO_SOURCE.
//       stpe2: invoke load() on the element and the load() rejects the pending promise.
// Expected result: reject the pending promise with AbortError DOM exception.

  //                  (2) invoke load() -> (1) set the networkState to be NETWORK_NO_SOURCE.
  //                                       (2) queue a task to run resouce selection algorithm.
