From w3c/pointerevents#381

Pointer Events link to 3 places in HTML that are not exported:

• html/#task-queue (from The pointerrawupdate event)
• html/#initiate-the-drag-and-drop-operation (from drag operation starts)
• html/#event-loop-processing-model | animation frame callbacks: not sure if we need a hook for step 12 (from animation frame callbacks)
