Illegal input string in Vector 2D when applied to hidden elements

When the behaviour is applied to an element whose parent has the attribute display:none, IE throws the above exception.

Thanks very much for reporting this. This looks like it's already covered already by issue #30 -- I'm closing this ticket in favor of the other one, but this is good as it gives an easy way to reproduce it.
