Description Tim Nguyen (:ntim) 2023-07-08 03:17:11 PDT 
sign(10px - 1em) should return 0 if font-size is 10px, right now it returns 1px, which is incorrect.

See failures in https://wpt.fyi/results/css/css-values/signs-abs-computed.html?label=master&label=experimental&product=chrome&product=firefox&product=safari&aligned&view=interop&q=label%3Ainterop-2023-mathfunctions

ditto for sign(10px - 2em), that should be -1 with font-size 10px.

round/mod/rem have similar failures with percentage lengths
