[Trinidad] bad position/size of tr:panelPopup after moving from 1.0.2 to 1.0.3

[Renzo Tomaselli]

Hi, after moving an application from 1.0.2 to 1.0.3, I noticed that all 
modal panel popups are now rendered in a wrong position and width. 
Height is ok.
With version 1.0.2 they used to appear ok.
This behavior is browser-independent (IE 6/7, FF 2.0).
Just flipping the Trinidad jar pair between 1.0.2 and 1.0.3 toggles this 
behavior.
