Forcing Asian fonts to conform to chat size

[Kanegasi]

I have my chat windows at size 10, but Asian fonts have their own size. I tried loading my own fonts.xml file hoping my heights would overwrite NumberFont_Shadow_Med (which is inherited by ChatFontNormal) but it does nothing.

I don't want to block these fonts (even though I can't read them) I just want them to be the same size as everything else.
