Rack from location children not available in floor plan tile

[albinpopote]

Environment

• Python version: 3.10.12
• Nautobot version: 1.6.1
• nautobot-floor-plan version: 1.0.0

Context

I have the following location tree implemented in nautobot:
Room-1 (Location Type: Room)
--> Row A (Location Type: Row - Children of Room Type)
--> Row B (Location Type: Row - Children of Room Type)
--> Row C (Location Type: Row - Children of Room Type)
--> Row D (Location Type: Row - Children of Room Type)

With some racks affected to the different rows:
- A0 --> Row A
- A1 --> Row A
- B6 --> Row B
- ...

Expected Behavior

When I want to create the Floor plan for my Room-1, I want to affect the rack A0 to the first line and first column
From the floor plan tile, I would like to be able to select all racks assigned to my room or whose room is parent to the location of my racks

Observed Behavior

Nothing is selectable under the floor plan tile
When I change a rack from Row A location to the parent Room-1, the rack is selectable

Steps to Reproduce

1. Create 2 types of Locations (Room and Row: Room is the parent of Row)
2. Create a Location Room and one or many Location Row(s) in the room
3. Create one or more rack unit affected to a Location Row
4. Create a Floor Plan affected to the Room
5. Try to select a rack in the Tile

I believe this is currently "working as intended". A Floor Plan Tile currently has a OneToOne relationship to a Rack, and a Rack currently has a ForeignKey relationship to Location (a single Location can have many Racks, but a Rack can only have a single Location). If I'm understanding your scenario correctly you want a Rack to be associated to both a Row Location (e.g. Row A) and a Room Location (e.g. Room-1) - which would not be allowed.
