Thanks for reporting this issue. Since I don't have any Apple device available, I can't reproduce the bug on it. However, the missing unit specifier affects the text rendering in Opera too.
I've added the "px" unit to the font-size attribute. As far as my recent tests can tell, it works fine and doesn't break the text layout created by SVG renderers that also create correct results without the additional unit (e.g. Squiggle).
