With Leopard introducing Grade 2 Contracted Braille throughout the OS, and Safari being an important part of that, WebKit needs to have a default stylesheet specifying which elements do not get contracted (e.g. dt, code, var, etc.)
Since contraction depends on content language, we'd need to fix the language inheritance before WebKit + Braille is usable to anyone.
Nick, could you please file a Radar for this? I believe that would help the issue to be properly prioritized.
Closing until CSS or PF Working Groups define a braille media type. Otherwise, this is not actionable.
