>From what I can see with a quick debug, when setting directly the font-size the rest of the other font properties are not set to a value which is fine as all the longhands (part of a shorthand) are behaving the same (for example, setting background-position only will not set other background properties to "initial"). Now the problem lies in the code reconstructing the font shorthand which assume that the font related properties were set using the font shorthand (which then will set the unspecified longhands to "initial" like any other shorthand) but as shown by the test case it's not always the case. I don't think Antti has anything to do with the problem, the bug has been there for a while I believe. I'll give a shot on a fix.
