[BUG] Trigger Tile Region Behavior

[Crowguard]

The Trigger Tile region behavior cannot have tiles added to it currently.

1. Dropping the tile as written does nothing; the tile is just moved behind the window.
   2. It does not accept the UUID.

Closing this. User error. Forgot you have to click the + button to save the UUID in there instead of just updating the entity config like every other UI in in Foundry.

Reopening. I forgot issue 1 is still a thing.
