This could maybe be addressed as part of #2515? https://drafts.csswg.org/css-cascade-4/#legacy-shorthand says

> CSSOM will not use them when serializing declarations

but I think they should be used when a longhand has a pending-substitution value linked to the legacy shorthand.
WebKit does this:

```js
style.pageBreakAfter = 'always'
style.cssText; // 'break-after: page;'
style.pageBreakAfter = 'var(--custom)'
style.cssText; // 'page-break-after: var(--custom);'
```
