+ Test for fetch and xhr to guarantee we only mark channel as urgent-start when
+ it is triggered by user input events.
+
+ For { Fetch, SRC-*, XHR }, do the test as following:
+ Step 1: Verify them not mark the channel when there is no any input event.
+ Step 2: Verify them mark the channel there is a user input event.
+ Step 3: Verify them not mark the channel when there is a non input event.
+
+ In each steps, it shows that we only mark channel on direct triggering task.
+ We won't mark the channel for additional task(setTimeout) or
+ micro-task(promise).
