MichaelW thanks!
A side note - you can have a doc comment above an interface, with @property annotation(s), i.e.:
/**
* @property bool $is_active
*/
interface imodel {}
or there is a @mixin doc comment annotation, which allows you to tell that members of another class will be available through IntelliSense, i.e.
/**
* @mixin ModelClass
*/
interface imodel {}
Anyways, the fix is on the way :)
