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<msup>
and<mmultiscripts>
and a bug with an incorrect applicationof the
superscriptshift
attribute has been fixed (see bug 827713 for details).
