Comment (by stumpc5):

 This just comes from
 {{{
 sage: t = StandardTableau([[1]])
 sage: isinstance(t,Tableau)
 True
 }}}
 and before trying to construct a tableau from some input this is tested...
 I wouldn't consider this a bug but more a feature: a standard tableau has
 all features of a tableau, plus extra. So for Sage users, I think this is
 the desired behaviour...
