For example, > div { padding: var(--x); padding-left: 0px; } would be serialized to > div { padding-top: ; padding-right: ; padding-bottom: ; padding-left: 1px; } which is apparently incorrect. It should be serialized to > div { padding: var(--x); padding-left: 0px; } This is probably tricky to implement. And actually Blink is wrong in the same way at the moment, so it is probably not a high priority issue. The spec seems to be correct that > shorthands that are specified with explicit var() functions must > serialize to the original, var()-containing value. [1] but there are probably some edge cases tricky to handle, which would need some investigation, and change proposal to the spec. [1] https://drafts.csswg.org/css-variables/#variables-in-shorthands

(I noticed this issue while looking at Servo's ShorthandID::get_shorthand_appendable_value function. This can be fixed after Stylo, so that we don't need to fix it twice.)
