dojo.html.getAbsolutePosition() not sufficient for determining layout coordinate in style - 0.4.3 tapestry script under firefox

Folks,

I rendered a gallery widget on a T-4.1.6 page, and ontop of each image I just create a text node as a child and write some transparent text. So it is rendering.... image with dom text noce positioned ontop (as a child)

In IE the child node places fine and I do not have to muck with position except for the X position (still do nto know why though).
