Gecko-specific notes
Starting with Gecko 9.0 (Firefox 9.0 / Thunderbird 9.0 / SeaMonkey 2.6)
labels are hidden by default (mlabeledtr > mtd:first-child {display: none}) and will longer break the table rendering completely (see
bug 356870
). For the actual implementation of this element see
bug 689641
.
