User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:22.0) Gecko/20100101 Firefox/22.0 (Beta/Release) Build ID: 20130627161625 Steps to reproduce: See http://jsfiddle.net/zBxug/5/ create a div with display: table-cell put an element inside that div with position: absolute apply any transform to the table-cell div Actual results: The absolutely positioned child element of the table-cell disappears. There have been other cases with more confounding css rules in which the element doesn't disappear, but appears in an unpredictable position outside of its parent table-cell. Also, inspecting the parent element in the Firefox inspector shows a dotted line drawn around the correct location of that parent. However, with a transform applied to the parent, the absolute child doesn't appear inside that dotted line. Expected results: The absolutely positioned child element of the table-cell should remain visible and correctly transformed.

Almost certainly a duplicate of bug 63895.
