Incorrect vertical alignment of tspan inside dominant-baseline
The attached file does not render as I'd have expected in FF 5. <text dominant-baseline="central"> <tspan>foo </tspan> <tspan>bar </tspan> <tspan>baz</tspan> </text> I'd have expected all three tspans to be aligned along the same "central" baseline. But for reasons unknon, it appears that each tspan except the first has its "central" baseline aligned to the "alphabetic" baseline of its predecessor. Makes vertical centering a real problem.
Agreed, I think the test should show all three tspans aligned on their central baseline.

(i.e. just using a <text> node in the reference case) Could you change the test (or add another test) that does that? r=me with that

I was expecting this not to work due to subpixel positioning differences but I seem to be wrong. http://tbpl.mozilla.org/?tree=Try&rev=8c780666adab
