AnimationNodeStateMachineTransition "at end" transition on looping animations

[PPillau]

Your Godot version:
4.1.1

Issue description:
One thing I am struggeling to understand myself as a new Godot user that would be awesome to add to the docs is if the SWITCH_MODE_AT_END SwitchMode of the AnimationNodeStateMachineTransition is also happening when the current animation is looping, or if in that case the transition is not triggered.
In the docs it says Wait for the current state playback to end, then switch to the beginning of the next state animation so I guess that means even for a looping animation "at end" transitions should be triggered, but that is actually not happening for me in the engine, so maybe that should be mentioned in the docs somehow...
