I have the same errors UIToolkit StyleAnimation issue transition property references non-set value when exiting play mode with active transition animation in the Unity editor. My UI is a tooltip, and I wanted to make a pulse animation in a loop (just change scale). Is it a bug or it must be done in a different way?
Unity version: 2022.2.0b4
uss
.animation-blink {
transition-duration: 0.6s;
transition-property: scale;
transition-timing-function: ease-in-sine;
scale: 1.05 1.05;
}
private const string _animationBlink = "animation-blink";
Awake
_tooltip.RegisterCallback<TransitionEndEvent>(e => Animation());
private IEnumerator Start()
{
yield return null;
Animation();
}
private void Animation()
{
_tooltip.ToggleInClassList(_animationBlink);
}
I have tried using Coroutine, UnregisterCallback in OnDisable and other things. Nothing help.

I found a solution by simply reordering UIDocuments in the scene: UITooltip is with a looping transition and no errors if it is above other UIDocuments.
Unity 2022.2.0b10 or sort order in the Inspector - still the same errors. The only solution is what I described above.
I also show you all errors:

Just found Unity - Manual: Create looping transitions but the issue still exists in play mode.
As I mentioned, if a UIDocument with a transition loop is under another UIDocument on the scene hierarchy and the transition started in play mode then exits play mode, the errors will spam the entire console.
I can’t make a transition in another UIDocument, only one and it has to be at the top.
Any comment, fix coming?
