+// This function triggers a long animation with two iterations, which is
+// *nearly* at the end of its first iteration.  It will hit the end of that
+// iteration (firing an event) almost immediately, 1ms in the future.
+//
+// NOTE: It's important that this animation have a *long* duration.  If it were
+// short (e.g. 1ms duration), then we might jump past all its iterations in
+// a single refresh-driver tick. And if that were to happens, we'd *never* fire
+// any animationiteration events -- the CSS Animations spec says this event
+// must not be fired "...when an animationend event would fire at the same time"
+// (which would be the case in this example with a 1ms duration). So, to make
+// sure our event does fire, we use a long duration and a nearly-as-long
+// negative delay. This ensures we hit the end of the first iteration right
+// away, and that we don't risk hitting the end of the second iteration at the
+// same time.
