Issue parsing CSS syntax "border-radius:0 0 100px 100px / 0 0 20px 20px;"

[ChrisCinelli]

It is a valid CSS statement for creating the bottom elliptical border.
However after less.js parses it, it becomes "border-radius: 0 0 120px Infinitypx 0 6px 6px; "
It looks like less.js try to calculate 120px / 0 but it is not the right thing to do here.
Note syntax "border-radius:200px / 100px;" is legal too in CSS.

 border-radius: ~"200px / 100px";

This takes it as a literal string without the normal math conversion.

Is this syntax finalized? I guess it has been stable enough with font declarations.
