Can't map to a category field in an entry sub-field

[daltonrooney]

Description

The entry type I'm importing to includes an entry field. Entries that can be related to that field have a category field, but that category sub-field is not included in the list of available element fields to map to when a new entry is created.

The category field does appear in the list of element fields if I import the feed directly to that entry type (rather than as a sub-field):
