  [css-properties-values-api] non-inherited custom property fails to inherit from parent when "inherit" is set
https://bugs.webkit.org/show_bug.cgi?id=251590

Reviewed by Antti Koivisto.

We would only look at the map of inherited custom properties when applying the "inherit" value
for a custom property. However, a non-inherited value should also use its parent's value in that
case.
