Explain this a bit more (why you need it last). I can see why but without the
context of this patch (making the enums match up with some other enum list) it
seems arbitrary.

also, same comment needed where you changed it above.

This is mostly paranoia on my part because of the various comments stating to
keep enums in sync. I'm not sure if we ever cast from a Blink enum role to a
Chrome specific one.

Added comment for the other instance.

       # Top level enums are in a namespace scope so the methods shouldn't be
       # static. On the other hand, those declared inline (e.g. in an object) do.
       maybe_static = '' if is_toplevel else 'static '
