Is this changing these to be optional (allow null)? Doesn't seem like the spec
has this.

Ah, I think I was trying something out. Fixed.

     [RaisesException, ImplementedAs=remove] void delete(DOMString property);
-    StyleValue? get(DOMString property);
-    sequence<StyleValue> getAll(DOMString property);
-    boolean has(DOMString property);
-    [RaisesException] void set(DOMString property, (StyleValue or sequence<StyleValue> or DOMString) value);
+    [RaisesException] StyleValue? get(DOMString property);

     iterable<DOMString, (StyleValue or sequence<StyleValue>)>;
     sequence<DOMString> getProperties();
 };
