   1 <!--
   2   This file is used as a control test to compare with the other Chrome Endure
   3   tests in perf_endure.py.
   4
   5   This file provides the ability to attach/detach a large DOM tree (also
   6   containing event listeners) in the live document.  It is meant to be the same
   7   as endurance_control.html, except it provides buttons that can be clicked to
   8   cause the DOM tree to be attached/detached.  This allows a control scenario
   9   to be driven by WebDriver, rather than being driven by the Javascript itself.
