 > Anyway, with 5.0a3 I get 54 fonts on a linux machine and 250 fonts on a
 windows machine. With the patches I get 21 fonts on the same linux machine
 and 250 fonts on the same windows machine. While I could understand the
 former the latter sounds like a bug (provided there are no issues with the
 test itself) to me.

 Okay, this was a bug on my side: I forgot the commit that added the font
 whitelist. Sorry, for the noise. Interestingly, the test on ip-check.info
 is falling back to the CSS test. I forgot how the code worked but one
 guess would be that it is doing this because it could not find any known
 font at all with JS...
