See also emilio's bug 1915980 comment 1. (All 6 of the bugs that are blocked-by bug 1915913 -- this one as well as that one -- seem to be essentially the same issue with sign(FOO - BAR) being rejected in various properties, where FOO and BAR are using different context-dependent units, which means the sign() expression can't be trivially resolved)
