in practice L22-29 is totally useless.  redefining initializePage (so this
method comes up first in the prototype chain) just to call the super's version
of this is useless.

additionally, a doc comment saying "Initializes * page" is also pretty useless
and should actually just be

  /** @override */

i've cleaned all these up here:

Thanks.

   };
 
   // Export
   return {
     FakeBluetoothOverlayParent: FakeBluetoothOverlayParent
