In the transpilation you created the field using

   registry.set(this, {id: 0})

in the constructor.  If you then claim that any write to the field can also create it, then you get the hijacking behavior which you wrote doesn't happen.

They just lexically scope the private names in their own separate namespace.  #foo refers to the innermost enclosing class that has a private field called foo.
