same directives with different require accessors are not injected properly

[Hotell]

in angular it's possible to inject same type of directives by require directive on itself and on parent via:
{require:['ngModel','^^ngModel']}

If I try do that within ngMetadata constructor I've got unefined formProvider

class SomeAttrDirective{
constructor(
  @Inject('form') @Self() form,
  @Inject('form') @SkipSelf() parentForm
){}
}
