   I'll have to think about those tests.  The obvious way to test 
whether a state is entered or not is to raise and event or set a flag in 
its onentry handler, but  history doesn't have an onentry handler.  
However it should be easy enough to test that the default executable 
content gets executed only the first time through the history state.

None of the existing tests was able to catch that bug (and it only occured when an initial element or attribute pointed to a history, not when history was targetted directly by a transition).
