--- Comment #7 from Antoine Quint <graouts at webkit.org> ---
So for the simplified height case, when ComputedStyleExtractor::propertyValue() is called we call into updateStyleIfNeededForProperty() and hasValidStyle() is true within that function so we do _not_ end up calling document.updateStyleIfNeeded().

In the simplified color case, we return false for hasValidStyleProperty due to this clause:

    if ((isInherited || maybeExplicitlyInherited) && ancestor.styleValidity() == Style::Validity::ElementInvalid)
        return false;

… and end up calling document.updateStyleIfNeeded() which then lets the transition start.
