+  Check that calls to beginElement cause the pause time to be updated.
+
+  This is an area that's underspecified so we're just going with what's
+  intuitive. A is supposed to start at the same time as B. However, whilst B is
+  paused, a script calls 'beginElement'. Yet A is not paused. Intuitively,
+  A should start at the time beginElement is called. However, unless we handle
+  this situation specifically, what happens instead is that A is considered to
+  begin at the time when B was paused as follows:
+
+
+    Document time:
+    0       1       2       3       4     ...
+  A:
+  B:        |.......*..........
+            ^ Pause starts here
+                    ^ beginElement called here
+
+  Intuitively, A should start at t=2s, not t=1s. To provide this behaviour we
+  must specifically handle it.
+
+  Perhaps a more fundamental question is whether a call to beginElement should
+  take effect whilst the document is paused. Currently it does. This is
+  consistent with Opera but not Safari.
