TrackEntry.set_mix_blend(SpineConstant.MixBlend_Add) is causing recursive additive even when both track entries are completed.

Using the "02-animation-state-listeners" Spine-Godot example, I replaced the "func _ready():" contents in GDScript.
https://github.com/EsotericSoftware/spine-runtimes/blob/4.1/spine-godot/example/examples/02-animation-state-listeners/animation-state-listeners.gd#L25
Replaced code:

func _ready():
	var spineboy = $Spineboy
	spineboy.connect("animation_started", self, "_animation_started")
	spineboy.connect("animation_interrupted", self, "_animation_interrupted")
	spineboy.connect("animation_ended", self, "_animation_ended")
	spineboy.connect("animation_completed", self, "_animation_completed")
	spineboy.connect("animation_disposed", self, "_animation_disposed")
	spineboy.connect("animation_event", self, "_animation_event")
	
	var animation_state = spineboy.get_animation_state()
	animation_state.set_animation("walk", false, 0)
	animation_state.set_animation("run", false, 1).set_mix_blend(SpineConstant.MixBlend_Add)
		
	pass

One of the arms is drifting away when both animation track entries completed their timeline cycle.

I hope that is explanatory enough to replicate.
