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!

Here's a simple example:

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.
