Gecko-specific notes

  • Starting with Gecko 26.0 (Firefox 26 / Thunderbird 26 / SeaMonkey 2.23 / Firefox OS 1.2) it is no longer possible to use <none /> as a child element. The rendering has been made more consistent with equivalent configurations of <msub> and <mmultiscripts> and a bug with an incorrect application of the superscriptshift attribute has been fixed (see bug 827713 for details).
