max(0, 1em, 2, 4px) //returns 4px on the basis of first enter basis. Previous calculation would result in max(2, 1em, 4px). Here, 2 and 1em is compared, 2 is returned. then 2 and 4px is compared. Resulting in 4px. max(0, 1em, 1, 4px) //max(1em, 4px)
Update functions.js

max(0, 1em, 2, 4px) //returns max(2, 4px) on the basis of first enter basis, as 2 gets em unit. Now em and px are incompatible till latest version of LESS.
