I don't think you need to WTFMove here, assuming value is a Ref<CSSValue>.

> +    return WTFMove(value);

Ditto.

Use a nicer variable name.

Use a nicer variable name.

Ditto.

Any reason why this isn't inline in the .h?

> Source/WebCore/rendering/style/StyleScrollSnapPoints.cpp:38

Ditto?

Can you do this in the class definition?

No reason! Moved to the .h (and made it inline)

>> Source/WebCore/rendering/style/StyleScrollSnapPoints.cpp:38

Done.
