It's specifically the local keyword (for the background-attachment longhand property) on this rule that we seem to be ignoring:
td#middle-cell {
background: url("support/500x500-red-with-green-center.png") local;
If I remove that keyword, Firefox doesn't change behavior; but Chrome changes to match our broken rendering.

table-cell-background-local.html , table-cell-background-local-002.html, and table-cell-background-local-003.html are almost certainly failing for the same reason. We've got newer bugs filed for those, but let's just track them in a single bug.
