The small dome light LED and frunk/trunk latch lights (among other things) are powered by the "consumer switched off" circuit. This circuit stays active for a while after the ignition is shut off to allow use of certain functions while the car is off (like power mirrors, seats, etc). Reports on the length of time that this circuit stays active are conflicting with some saying as little as 3 minutes and others saying as much as 3 hours.

Can you confirm that the dome LED never shuts off, even after sitting overnight for 8+ hours?

Opening a door reactivates the circuit, so Steve may be on to something.
However, it would take roughly 100 LEDs to draw 2.6 amps.
There are about that many between the 986.2 gauge cluster, climate control and switches...
