Fixed background image bug in table elements

Steps to reproduce:
Define a background-image with background-attachment:fixed for either of td, th, tr, thead, tbody, tfoot or the respective display:table-cell etc. Then scroll.
Expected behaviour:
The background image should be fixed when scrolling
Buggy behaviour (marked with red border below):
The background image will not stay fixed when scrolling. Sometimes it scrolls, other times it breaks, sometimes it updates to the fixed image. When refreshing the page, the image will repair to the fixed image position.
Notes:
Fixed background images on table or on div within td, th, or display:table-cell are not affected (marked with green border below).
This bug affects Firefox 36.0 on Windows 8, Mac OS X, or Ubuntu. Neither Google Chrome nor Safari are affected by this bug.
