When using fuzzy matching to match entity names for intents, whichever
entity is first is preferred in the case of equal matches. This leads
to situations where entities with similar names (such as entities named
for their area and then specific area location) may be used when the
whole area is wanted.
I ran into this with the my Phillips Hue lights. I have each individual
light named such that its room is the first part of the name, and its
location within the room after. So my living room has:
Living Room West
Living Room Northwest
Living Room North
Living Room Northeast
I then have a group for the whole room:
Living Room
Because the group is the last of the entities, trying to adjust the
whole room only activates one light, because all of the lights match
equally well.
By preferring the shortest of equal matches, we prefer keys that have
the least amount of extra information, causing "Living Room" to match
the group instead of an individual light.
