"""Tests events for an extended sequence of pointer moves and clicks."""
# This test generates an extended sequence of pointer move and click events,
# and verifies the corresponding sequence of pointer, mouse, and click events
# dispatched to the HTML elements. The test includes use of pointer capture and
# use of preventDefault() and stopPropagation() on the events, as well as event
# bubbling.
