Very simple example showing what it is like to get the property value and mismatch currently in FF nightly implementation: Those assigned in a stylesheet are trimmed (which is nice) and those inline are not (which kinda sucks but might actually be proper as it's just tokens)... Either way they should match.

console.log("computed style of documentElement: '%s'", window.getComputedStyle(document.documentElement).getPropertyValue("--x-thinger"));
