Eventually, it'd probably be ideal to make MathML content in vertical writing mode work "correctly", by rendering it as if with text-orientation:sideways-right. But that will require logicalizing a whole bunch of mathml layout classes so that all the x/y positioning behaves in the appropriately rotated way.

Until we're ready to tackle that, let's simply make all mathml have writing-mode:horizontal-tb by putting this in the UA stylesheet.

In bug 1095933, horizontal mode is only forced on the <math> root. shows that the property can still be set to change the MathML layout.

Let's force horizontal-tb on all MathML elements for now, as suggested by
