Beschreibung

Currently direct `HasTraits` subclasses warn when they receive unrecognized arguments:

https://github.com/ipython/traitlets/blob/b0eaa6aa77e198cff68644a388400db850670c7d/tests/test_traitlets.py#L2802-L2810

However, this does not work with `Configurable` and its subclasses, although it is a subclass of `HasTraits`:
