Description (include any images, videos, errors, or crash logs)

tried it with frame indices then tried it with frame labels and then tried setting all the symbols to play once then tried debugging it and found out the "isAnimationFinished" function is broken in animate atlas characters and maybe even in animate atlas in general

Steps to Reproduce

make an animate atlas character with -hold animations
test the character
