Safari and Chrome both pass this.

Comment 2

[Daniel Holbert [:dholbert]]

It looks like we're failing (rejecting at parse-time) the cases where the subtraction has different units, e.g. calc(sign(20rem - 20px) * 180)

Reduced testcase (check in devtools to see if it parses or not; it doesn't right now, in Firefox, but it parses fine if you change the units to match):

data:text/html,<div style="border-image:calc(sign(20rem - 20px) * 180)">
