Feature definitions attribute is empty for an existing FeatureGroup

[cpting]

Description
The feature_definitions attribute of an existing FeatureGroup is empty, although you can get the list of the real feature definitions associated with that FeatureGroup when you do feature_group.describe().get("FeatureDefinitions")

Expected behavior
The feature_definitions attribute would also contain the existing feature definitions as returned in the describe() call.
