Can you link to the spec in a comment? This is a really weird list.

I found some mistakes in the condition. We don't need "CSSPropertyWidth" and
"CSSPropertyHeight".

I fixed.

Sure. I added a comment, but the comment is not related to the spec.

Because we need "CSSPropertyFont" and "CSSPropertyMarker" because of Blink
implementation.
So the comment explains why we need to check the two properties.
