field's tooltip doubling on validation error

I have a form with fields. Those fields have description tooltips, set by “setDescription”.
When the field is being validated unsuccessfully it shows two tooltips on mouse hover. The first
one is for error message and the second is for description.

It looks not realy good. I think the better behaviour could be to show only one tooltip that is indicating erronious input, suppressing the second.

Is there any elegant solution for this?
