I'm sure it was temporary because I have just tested what you suggested. It was present in 3.0~b3~cvs20080101t1000+nobinonly-0ubuntu1 but now I was unable to reproduce it! I now have 3.0~b3+nobinonly-0ubuntu2.
I also tried changing default size down to 15 which I think I had before and also tried minimum of 11 and 13 but both worked. Firefox seems to be fixed.
