Issue description

AnimationTree repeats the methods and properties that trigger the last frame of the acyclic animation.
I only pressed the button once.
As shown in the figure, I don't know whether it is a bug or a feature?
How can I keep the last frame of the current animation instead of switching to the next animation to solve this problem?

AnimationTree 会重复触发非循环动画的最后一帧的方法和属性.
我只按了一次Button.
如图所示,不我知道是BUG还是特性?
如何可以保持当前动画的最后一帧,而不是切换到下一个动画来解决这个问题?
