having trouble with the attachTo property

[aiesst]

Hi, I'm experiencing an issue with the attachTo property in my code. Regardless of whether I set the on attribute to 'top' or 'bottom', the tooltip always appears in the top-left corner with the following CSS:

position: absolute;
left: 0px;
top: 0px;

Here's the relevant part of my code:

attachTo: {
    element: elementSetupOne,
    on: 'bottom'
}

It seems like the left and top values are always set to 0. Has anyone faced a similar problem or have any ideas on how to resolve this?
