Those should be defining properties, not setting them.  Furthermore, those
properties should have some non-default property attributes (which you have to
think about once you start defining properties).  In particular, the
.constructor of the prototype should not be enumerable (because otherwise
enumeration on all the elements involved would see it!), and the .prototype of
the constructor should probably not be configurable, writable, or enumerable
(which is how WebIDL .prototype and standard class .prototype work), though
this part we could at least argue about.
