Support for the universal or "CSS-wide" property values (
initial,inherit, andunset, see https://www.w3.org/TR/css-values/#common-keywords) is mixed at the moment.Several properties manually are defined to allow
initialandinherit, currently:Separately,
inheritis allowed for every property, but only in thestyleattribute, not in an extracted style block (the code that does this is only in the CSS AttrDef).This PR removes the special case in AttrDef_CSS and the explicit enum definitions in the CSSDefinition, and replaces both with checks in AttrDef_CSS and Filter_ExtractStyleBlocks against an enum of
initial,inherit, andunset, making all three values allowed for all defined properties in both the attribute and block contexts.unset, which hasn't previously been allowed here, is comparable toinitialandinherit: for properties that inherit by default, it acts asinherit, for those that don't, it acts asinitial.
