You say that it doesn't apply for the size of 'font'. The link above uses

font:60 serif

and has a 60px font size in Firefox Nightly for me.

These also get applied:

font:101 serif
font:100 60 serif
font:100 100 serif
font:bold 100 serif
font:normal normal normal 100 serif

These don't:

font:100 serif
font:100/1 serif
font:normal 100 serif
font:normal normal 100 serif
