absolute positioning from a parent element doesn't work in a jquery UI v1.8.4 dialog box. I'm having a hard time coming up with a workaround for what I need, so figured I'd post this issue here and see if there's a potential fix?
Basically, if you have a div (doesn't matter how nested it is) with css position:relative inside a jqueryui dialog, and then inside that div you have another div with css position:absolute, the inside div will be positioned relative to some other element (an unknown element which is not the parent).
However, if you resize the window even just 1 pixel, everything works perfect from then on!
Setting the height to a pixel value in the dialog options fixes this issue. However, that doesn't work for me because I don't know how tall the dialog should be at runtime... Note that the issue here is not that the parent element has height=0 as experimentation will show.
