Should Version be changed to Trunk? Or has this already been fixed on the trunk?

This is not fixed on Trunk. Changing Version to Trunk, as I expect this'll be fixed on trunk before it is on 1.8.

Partial support this font is now on trunk. Unicode parts for stretchy chars are available from bug 400938. Bug 289938 needs to be fixed for Unicode Plane 1 characters. This font has no italic nor bold style for alphanumeric characters in plane 0 as they exist at their unique code points in plane 1. To ensure that <mi>a</mi> is displayed as italic we either need to complete the mathvariant translation to plane 1 (bug 114365) or we need to ensure that synthetic italic and bold are functional (e.g. bug 333126). Currently the font-family in mathml.css has "Cambria" before "Cambria Math" to work around this issue, but "Cambria" should be removed once this issue is resolved. The radical symbol bottom is available in this font and can be extended with U+20D3 COMBINING SHORT VERTICAL LINE OVERLAY, but there is no character mapping to the glyph for the top of the stretchy radical. If the change to the radical rule alignment code suggested in Bug 403958 is made, then adding a mathfontCambriaMath.properties would enable use of this font to build radicals of any height. Bug 407059 is the best way to get the non-Unicode size-variants and parts for stretchy characters, as there are no character maps for the non-Unicode glyphs.

I'm closing all these font-specific meta bug since the main work has been done in bug 407059 and bug 947650. Remaining issues will be handled on the OpenType MATH bugs. Once bug 1000879 is merged, one will be able to verify the initial OpenType MATH support with the MathML torture test: https://developer.mozilla.org/en-US/docs/Mozilla/MathML_Project/MathML_Torture_Test
