Classes nested within top-level classes are not namespaced correctly in the left-hand menu

[shicks]

Example:

goog.module('Foo');
class Foo {}
Foo.Bar = class {};
exports = Foo;

This produces classes Foo and Bar in the left-hand menu. If, on the other hand, I write

goog.module('ns.Foo');

then the left-hand menu is correct: under ns is Foo and Foo.Bar.
