Where is this is the spec? I could not find those normal attributes at:
https://drafts.csswg.org/cssom/#the-cssstyledeclaration-interface

Is our behavior really standard? Do other browsers really behave the same way as us?

That spec has crazy formatting for me :(.

The property bits are defined in:

https://drafts.csswg.org/cssom/#dom-cssstyledeclaration-camel-cased-attribute
https://drafts.csswg.org/cssom/#dom-cssstyledeclaration-webkit-cased-attribute
https://drafts.csswg.org/cssom/#dom-cssstyledeclaration-dashed-attribute

Note the text like:

"For each CSS property property that is a supported CSS property, the following partial interface applies where camel-cased attribute is obtained by running the CSS property to IDL attribute algorithm for property."

Not sure what the compat story is here. I tried to minimize behavior change as much as possible here. Matching other browsers and the spec can come next.

r=me with comments.

> Source/WebCore/bindings/scripts/CodeGeneratorJS.pm:906

nit: Variable name should have "is" prefix.

> Source/WebCore/bindings/scripts/CodeGeneratorJS.pm:965
> +        if ($namedSetterOperation->extendedAttributes->{PutOnlyForSupportedProperties}) {

Isn't this confusingly named? What the code seems to do is call JSObject::put() if the property is NOT supported. The name seems to indicate the opposite.

> Source/WebCore/css/CSSStyleDeclaration.h:74
> +    // Bindings support

Missing period at the end.

> Source/WebCore/css/CSSStyleDeclaration.idl:49
> +    // recosider this decision.

Typo.

Yeah, I guess. I was thinking of Put as meaning the custom setter, but that is not at all clear from the name. Renamed it to [CallNamedSetterOnlyForSupportedProperties].
